I used to use 1.2.3.4 as my gateway.
At the time I didn’t understand why this offended … Basically everybody.
As a Network Engineer: If you did this in my presence, I’d burn you at the goddamn stake. 😂
Like I said … Basically everybody.
That’s mostly because it violates established standards, but you know that already. Lol.
Also, if you’re talking to a network engineer, they probably have PTSD dealing with a client that did this with a 1.0.0.0/8 used internally or some shit and now huge swathes of the internet doesn’t work, but somehow it’s “our fault” that they can’t load random web sites.
Fwiw, I now use 10.10.220.0/24. I now know what class A, B and C are. I didn’t then.
Hopefully that offers you some comfort.
Thankfully, the internet is now as classless as I am. I don’t miss having to align to those.
Everyone knows you need to be using a network like fd25:c74c:a5e9::/64. So much more fun that way.
I’m sure this is hilarious, but I don’t know enough about IPv6 to get it.
It’s just a ‘proper’ IPv6 private address, the IPv6 equivalent of ‘10.’.
I say proper as a private address in ipv6 is supposed to be fd, then 40 random bits, then whatever you want. Nothing stops you from having fd::/64 as your private network though. The thinking was people who got tired of merging networks that happened to choose the same 10.x.x.x scheme and/or vpn connecting to multiple sites similarly with the same private address. So they thought it would be swell if every private network on earth would likely be unique, so they said you ‘must’ randomize 5 bytes of it. Then no renumbering/no conflicting vpn connections.
Haha all good homie.
That’s mostly because it violates established standards, but you know that already. Lol.
Hey, for all you know he might actually be the proper owner of that subnet…
I know if by some crazy coincedence I had that in my subnet I’d be using it for fun.
I recently had a ticket for a university that had a /12 of public IPs. They gave every computer, printer, etc. a public IP on their whole network. Nothing has NAT. It was insane. They could buy an entire other university building with the money they’d make selling some of that address space down to even a /24.
10.0.0.0/8 address space with a gateway address that gets randomized every 24 hours. Tomorrow’s address is advertised on a HTTP server local to the network that cannot be externally accessed. For security reasons.
That’s the kind of overengineering I was hoping for!
Nothing advertises hostnames, and the DHCP table is dumped and every client gets new address at the same time, too.
Just make sure the MAC addresses randomize, too, and then you’ve got yourself a proper fucking mess for a hacker to sort out.
Throw in some random static DHCP leases that cycle every hour and update the firewall rule alias

I use 10.13.37.42 as my gateway.
Why not 10.69.42.01?
I have never found the number 69 joke/reference funny, just annoying.
You are very welcome to use that IP adress yourself, but I am going to stick to 10.13.37.42
Sigh why on earth did I not do 10.13.37.0/24?? Mine is lame as hell
Gateway is .69
Dhcp is .70 - .254
Static routes are .68 and below
I will not be taking any questions
The “gateway” is 69. Noted
No no no, the period comes first, .69
Gotta get your red wings.
I understood that reference…
Also, I’ve got those. 😏
About twenty years ago I was hired in to straighten up a network at a investment place. They were running all static IP addresses and the guy who set it up set the gateway to 69. I laughed and started converting them to dhcp and seriously considered leaving the gateway alone.
I have to ask a question now. My question is, is that you?
It wasn’t me. Why leave room for DHCP if you’re not going to use it?
Gateway has multiple IP addresses, from .1 through .10 . (I used to have multiple OpenWRT servers for different things, but consolidated them all into a single rackmount server.)
There’s nothing preventing the gateway from being a DHCP client, just saying…
oh my god
i love this idea so much. I’ve been doing networking for 13 years now and I’ve never considered a dynamically addressed gateway
also servers
At first I didn’t understand then I read your comment… oh, my, god!
your home router is a DHCP client of your ISP’s DHCP server, so…yea.

Last address? Who the heck does that???
I’ve had modems from my ISP which assigned themselves 192.168.0.254 for some reason. I have no idea why
My guess is that enough people were buying routers and using them as access points. They all tend to be on 192.168.0.1 .254 means you don’t get as bad collisions when that happens. It would cut down on technical support calls.
It’s called
multicastedit: broadcast and it’s for spamming every device on the network /sIt’s called multicast
Don’t confuse the broadcast address with multicast!
hey, don’t you blame multicast for the sins of others! Multicast and Anycast are under witness protection!
I work for a French company that does this, I don’t know if all French companies do this, but it threw me for a loop for sure.
There are reasons to put it at the end. For example, 192.168.1.254/24 can be expanded to /23 and have the same gateway address while you migrate clients that are statically assigned or while waiting on DHCP leases to expire, since /23 is a supernet of /24.
10.10.0.254 here, because I wanted my main rig to be .1
Use .0, it’s free real estate.
A typical ip address scheme is to assign lower blocks to dhcp pools and reserve high ip addresses to servers and network gear. Anything over 250 is typically a switch or a router in this case.
Meanwhile my gateway is
fe80::17a9:3ba7:5¥4🐔:b8ä7%42Wait is there an existing unicode to ipv6 method. I assume it would just be the bit values of the emoji in utf8?
fe80::“hello 🐔” aka fe80::6865:6c6c:6f20:f09f:9094
I approve of the idea of cursed ipv6 notation.
That would be a funny way to avoid DNS, just make the address the name.
https://github.com/zhoreeq/meshname/blob/master/protocol.md :
IPv6 address is converted to its binary form {…}; The binary value is encoded to base32 (RFC 4648) {…}; Padding symbols “======” are removed from the end of the string.
You can now put text into the address like with .onion sites, or session messenger nicks.
I was joking, but it would be cool if each segment could be rendered as a UTF-8 glyphs.
sup
R U local?
I’ll be everywhere…wherever you look. Wherever there’s a fight so hungry people can eat, I’ll be there. Wherever there’s a cop beatin’ up a guy, I’ll be there. I’ll be in the way guys yell when they’re mad…I’ll be in the way kids laugh when they’re hungry and they know supper’s ready. And when our folks eat the stuff they raise and live in the houses they build…I’ll be there.
I love that people forget about 127.0.0.0/8 being the loopback network. Everyone just uses .1 when there are so many to choose from.
According ding the the law of minimal keystrokes, there’s actually only 9 to choose from.
After applying the law of minimal motion, you’re down to even fewer.
Then you go a step further to just using 127.1 (or your preferred last digit)
IPv6: Fuck you, you’re only allowed one, now. Yeah, yeah, I know there are about 340 undecillion addresses in the space, but I know better than you, no one in history has ever needed to bind different services to the same port on the loopback interface, and if they did they were doing it wrong. Oh you made an RFC draft? Well I let the one from
20152012 expire, so good luck with your current proposal, pleb.Can’t you just use a ULA address for that?
So the onus is on every individual user, to pick a random ULA prefix, bind specific addresses from it to the loopback interface, which is a different procedure for different OSes, probably requires root or elevated privileges, can have hard limits on, document it, etc. Greeeeaaaaaaat design. IPv6 gives out
/64like they’re about to turn bad, but can’t spare a/104? Gimme a break.I can dig a hole with a spoon, too, but if someone made it so that no one was allowed to dig holes with shovels unless they build their own (and have permission to build the shovel), when previously everyone was allowed to dig with shovels, I would not think highly of that person’s wisdom.
Maybe you think G. Huston of APNIC and W. Kumari of Google don’t really know what they’re talking about?
I don’t bother with ULA addresses on my home network and just use the public /56 I have broken into various /64s for each VLAN I have. In a corporate environment, I might use ULA addresses, but since IPv6 is “everything is public by design” and an Enterprise will have a static IPv6 block, if they did it right, it’s not like it’ll change. And for anything that doesn’t need internet, link-local is a thing.
IPv6 isn’t perfect, but I find myself liking it more and more as time goes on. Some of it is habits. Some of it is that I tire of dealing with things like CGNAT and SIP.
Subnet: 10/8
Gateway: 10.2.5.5Thanks. I hate it.
Just set the Gateway to use DHCP.
Settle down Satan
So statically assign all IPs except for your gateway?
Nah, put your gateway in a different subnet, but on the same network segment, and add a static /32 route to it on every client.
Is there a specific reason behind this? Never considered it but I could see it being useful since most specific routes win.
Mostly to make the next sysadmin (or yourself in 6 months) weep. There’s nothing preventing there being multiple IP subnets on a single network segment, but you’d usually handle that with separate VLANs, or at least an interface alias, so the machine saw both subnets. About the only reason I could see for just adding a static route would be if you’re in the middle of reconfiguring your network to a new subnet but you still need the hosts you haven’t updated to be able to route.
The real nightmare when someone puts two ip addresses on the same host through different interfaces. Now that makes for some confusing troubleshooting and explanations in various applications.
What really gets me is in about 3/4 networks in the last couple of weeks I’ve been asked to help troubleshoot, the problem has been duplicate IP addresses. I don’t know what is going on with people…
That won’t work, unless I’m misunderstanding you. You’d still need a gateway within your subnet to handle inter-subnet routing or an additional address on the gateway network.
It can be made to work, just really really stupid.
Ultimately the ‘gateway’ is really a mac address, and the IP is just the thing to ARP to get the mac address. And you can do some gnarly things to pull off things like off-subnet gateway addresses.
You should never ever do it, but you can if you hate yourself enough.
Becomes easier in IPv6 to do these shenigans too.
Technically, sure, but you have to do a ton of fuckery and I have no idea why anybody would do all that work rather than just use an IP in the subnet.
By adding a host, or /32, route to the gateway you should then be able to use it as the default gateway on your main subnet. I was not being serious when I suggested it, as another comment says, it’s a pretty stupid idea, and there really isn’t any sane usecase for it, except possibly one of those 1am “if it’s stupid but it works it’s still stupid, but it’ll do until morning” type fixes that you shudder to recall years later.

I’m the cat
1 is my pc. 254 is the managed micro switch i use to isolate work stuff. Most things are neatly arranged - eg: 70 is the testbed proxmox, 79 is its idrac, 71-78 are the vms, same with 80 on my production proxmox. DHCP is zoned from 101 to 199, IoT are assigned fixed IPs in similar ranges, etc.
Modem is 11
Danny John-Jules?!
wrowling noises
Who hurt you?
No one. And even funnier? I do this shit professionally
Lol you fucking psycho. Love it.
Cant hack the gateway if you cant find it!
My home server is at 192.168.1.230 because that’s what IP was assigned to the machine at the moment I set it up.
Yep. Love that chaos, ya know?
DHCP gave me 170. I said “let’s make this static shall we?”
Back before i knew anything about networking and set my desktops with statics, i had .1-9 as user devices, .10-19 as servers, .20-29 as printers, .50-59 as networking devices. So my current server is .14 and has been that since uni, DNS is .50, gateway is .51. Now my dhcp pool starts at 100.
Lol mine is .116 for the same reason
Lol, same-ish, lazy gang ftw.
There are dozens of us
First address? As in, the network address? Last address? As in, the broadcast address? Suspicious.
This guy networks
/31, looking shady since 3021
*First Usable Address. Obviously u can drop the usable part.
Also change the random address daily without announcing it. If the 7th floor wants internet they can damn well work for it. 😆
