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.

Thatβs 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
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. π
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.

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. π
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?

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

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

It's called ~~multicast~~ edit: broadcast and it's for spamming every device on the network /s

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)

Meanwhile my gateway is fe80::17a9:3ba7:5Β₯4π:b8Γ€7%42
Wait is there an existing unicode to ipv6 method. I assume it would just be the bit values of the emoji in utf8?
fe80::"hello π" aka fe80::6865:6c6c:6f20:f09f:9094
I approve of the idea of cursed ipv6 notation.

Subnet: 10/8
Gateway: 10.2.5.5
Thanks. I hate it.
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.

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?

First address? As in, the network address? Last address? As in, the broadcast address? Suspicious.

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

Also change the random address daily without announcing it. If the 7th floor wants internet they can damn well work for it. π
10.10.10.70 here. There was a reason in the distant past that I did this and now it's stuck that way forever.
