Peering Guidelines

  • WireGuard tunnels is used.
  • IPv6 is done with Link-Local addresses.
  • IPv4 is done with unnumbered interfaces (a.k.a. /32) addresses.
  • Multiple links is prefereable. But not required.
  • Closest geographical locations is chosen for peering link to minimize latency.

Looking to peer with me. Please see contact details in about.

Routing policy

  1. ROA validation is used for all ingoing and outgoing BGP announcements. Invalid announcements is rejected.
  2. The below prefix filter rules from the dn42 website is used, too.
  3. All route announcements with as-paths longer than 32 is rejected. (This is to prevents a mishap in the event of an unlikely routing loop in the network)
