About Tank (and the site)
A short bio of a long cat, plus why this site exists.
Tank, briefly
Tank is a brown tabby with white paws and chest, currently age 4, who lives in northern Vermont. He weighs more than he should, sheds with industrial enthusiasm, and is generally annoyed but never aggressive about it. He sleeps about 16 hours a day, occupies whichever chair you most want, and silently judges every video call.
His role on this site is straightforward: he holds up a piece of cardboard with your IP address written on it. He was not consulted on this. He has no ownership stake in the company. Treats are involved.
Why a cat-themed network site
Most "what's my IP" sites are aggressively bad. Stuffed with autoplaying videos, fake virus warnings, popunder ads, dark-pattern "subscribe to our VPN" walls, and a banner that says YOUR LOCATION HAS BEEN DETECTED! in red. The information density is roughly: one IP address, fifty distractions.
I'm a network admin. I look up IPs all the time. I got tired of the ad-rotten experience and figured a cat could do the job better.
So this site does what those don't: it shows you the IP, fast, on a piece of cardboard held up by a tabby cat. Then below the fold, it has the network utilities you actually use — subnet calculator, port reference, MTU calculator, that kind of thing — without 14 modal popups asking you to subscribe to anything.
Who built this
My day job is network and IT administration — Proxmox homelabs, UniFi networks, FreeSWITCH PBXes, the kind of stack where you accumulate strong opinions about subnet sizing. Tank lives with me. Both of us thought this would be funny.
Money stuff
The site runs Google AdSense. That pays for the domain and bandwidth. We don't sell your data, we don't have hidden affiliate links sprinkled through the calculators, and we don't have a "premium" tier. Everything is free, every tool runs in your browser, and nothing you type is sent to us.
Bug reports and feedback
If something is wrong — a calculation is off, a port assignment is missing, the cat looks too smug today — tell us. We read everything.
