IPv4

  • 23.161.208.0/29 - mail servers (actually part of apps-vm6)
    • 23.161.208.7 - Email to University of Illinois at Urbana-Champaign
  • 23.161.208.8/29 - NAT pool for external access
  • 23.161.208.16 - 23.161.208.127 - external access delegated subnets (/32 - /28, up to 16 IPs per subdelegation)
  • 23.161.208.128 - 23.161.208.223 - reserved for future use
  • 23.161.208.224/28 - NAT64 pool (future use)
  • 23.161.208.240/28 - apps-vm6 superhost
  • For a detailed list of assignments, see List of port assignments used by apps-vm6.
  • Note: In all the above delegations, there are no network or broadcast addresses. All IP numberings begin at the first address (e.g. .0), not .1. See IP Configuration Rant.

IPv6

  • 2602:806:a000::/48 - apps-vm6 static delegation
    • 2602:806:a000::/64 - internal apps-vm6 use
    • 2602:806:a000:4000::/50 - external access delegated subnets (/128 - /112, /96, /64 - /56)
    • 2602:806:a000:8000::/51 - apps-vm6 superhost
    • For a detailed list of assignments, see List of port assignments used by apps-vm6.
  • 2602:806:a001::/48 - home network
  • 2602:806:a002::/48 - anycast
    • 2602:806:a002::123 - NTP service
  • 2602:806:a003::/48 - apps-vm5 delegation
    • 2602:806:a003:40e::/64 - Nginx-40e
    • 2602:806:a003:40f::/64 - Router Hop Generator
    • 2602:806:a003:4ff::/96 - Container bridge subnet
    • 2602:806:a003:40f::ece:374 - GitLab (direct)
    • 2602:806:a003:4ff::ece:385 - GitLab (Cloudflare)

Each delegation may only have one IPv6 subnet/route, unless the existing allocation needs to be expanded and it would overlap with another delegation.

Please note that traceroutes to 2602:806:a003:40f::/64 may return repeated or alternating addresses. This is completely normal for the operation of Router Hop Generator and is NOT a routing loop. See Router Hop Generator for more information.

Note

Subdelegations can be given:

  • One carrier-grade NAT IPv4 address, optionally up to 16 (a /28 of) IPv4 addresses, plus any port forward rules from the shared NAT range. An additional subnet of up to /24 of carrier-grade NAT addresses can be routed.
  • One globally routable IPv6 address, optionally up to a /56 of IPv6 addresses.
  • When the NAT64 service becomes operational, IPv4 addresses will likely no longer be needed.

I am legally not allowed to be an Internet Service Provider except for providing service to myself, and even then it's limited to professional work only. I will, however, be able to demonstrate how I would serve a customer as if I were to work at an ISP.
