DN42 Peering

DN42 is a decentralized private network where participants connect using BGP and private IP addresses. Think of it as the internet in miniature — real routing, real peering, no consequences. You build tunnels, exchange traffic, and learn BGP without accidentally breaking anything important.

My DN42 autonomous system AS26954 (AS-KOLO-DN42) matches the real internet ASN and is connected via WireGuard or ZeroTier tunnels.

Peering

Peering is possible over physical or VLAN attach, ZeroTier, WireGuard, and clearnet Internet Exchange points.

Tunnels over WireGuard, ZeroTier, GRE/SIT, or whatever else; BGP as MP-BGP with Extended Next Hop, or separate IPv4/IPv6 sessions.

For peering requests, mail our magnificent network operations team at [email protected].

Brutal Russian internet censorship can make tunnels to the Moscow node unreliable or unpredictable — IPv4 is preferred.

The Tel Aviv-Yafo node was decommissioned due to insane and inhumane prices.
