Show HN: Chat with people who share the same Internet connection (= IP address) (ipchat.org)
17 points by kkovacs 3 months ago | hide | past | favorite | 17 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. :)



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 :)

Looks like a chatroom. What about private messaging


What OS, window manager, etc is this?

That could be a logical next step!


Is the source published somewhere? I would love to run this on premises.


Hey developer please add filesharing capabilities even if 5mb cap


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.


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? ;)


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