Show HN: Chat with people who share the same Internet connection (= IP address)

[kkovacs]

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

[kkovacs]

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

Looks like a chatroom. What about private messaging

[leoh]

What OS, window manager, etc is this?

[kkovacs]

That could be a logical next step!

[davidcollantes]

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

[edmundsparrow]

Hey developer please add filesharing capabilities even if 5mb cap

[edmundsparrow]

This is cool. I can use this on gnokestation

[kkovacs]

Thanks for the encouragement, Edmund!

Dude, IPv6… We are in 2026.

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

[zinekeller]

Yeah, it should probably be /64 for IPv6

[kkovacs]

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