Show HN: Chat with people who share the same Internet connection (= IP address)
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. :)
- dClauzel 9mo agoDude, IPv6… We are in 2026. The GUA are 128 bits, every one of us is alone.
- kkovacs 9mo agoYou would be surprised how many of us are on IPv4 :) With GUA, who needs tracking cookies? ;)
- proactivesvcs 9mo agoi netted six alone in a scope of the entire globe, temporary, dynamic.
- zinekeller 9mo agoYeah, it should probably be /64 for IPv6
- kkovacs 9mo agoCould 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.
- baobun 9mo agoI guess this could be fun for people using shared VPN and proxy services
- kkovacs 9mo agoHeh, I never thought about that, but it's true.
- kimchidude 9mo agoUshering in the Silk Road 2.0 haha
- kkovacs 9mo agoLet's hope this not end with me taken away in handcuffs, lol :)

- davidcollantes 9mo agoIs the source published somewhere? I would love to run this on premises.
