Show HN: Chat with people who share the same Internet connection (= IP address) (ipchat.org)
14 points by kkovacs 21 hours ago | hide | past | favorite | 15 comments
I built a simple, ephemeral chat service that connects you only with users who share the exact same public IP address as you.

It's essentially a temporary, isolated chat room defined by your NAT gateway.

It's not super useful nowadays, but let's see where this takes us. :)

Looks like a chatroom. What about private messaging


That could be a logical next step!

What OS, window manager, etc is this?


I guess this could be fun for people using shared VPN and proxy services

Heh, I never thought about that, but it's true.

Ushering in the Silk Road 2.0 haha

Let's hope this not end with me taken away in handcuffs, lol :)

This is cool. I can use this on gnokestation

Thanks for the encouragement, Edmund!

Dude, IPv6… We are in 2026.

The GUA are 128 bits, every one of us is alone.


  i netted six
  alone in a scope of the entire globe,
  temporary,
  dynamic.

Yeah, it should probably be /64 for IPv6

Could be done, but nothing is EVER simple regarding IPv6. :) What about EUI-64? Any special cases regarding TEREDO, ORCHID2, 6to4 addressing scheme (NOT the same as NAT64!), etc...?

Nevertheless, something like this could be an option.


You would be surprised how many of us are on IPv4 :) With GUA, who needs tracking cookies? ;)
