Every address answers under a domain named after a different AS number than the one announcing it.

What it's used for

  • A fibre provider's network. 256 addresses in the single IPv4 prefix 45.45.169.0/24, the IPv6 block 2602:f6ad::/40, and one observed BGP neighbour.

Notable

  • All three sampled addresses answered, as 45-45-169-64.ipv4.sdf.as32030.net and similar.
  • The domain in those names is built from an AS number that is not this one.
  • The names also carry an address-family label and a three-letter site code between the address and the domain.
  • The block is netname BFG-VCI-NET1-V4, which marks the address family a second time.
  • The IPv6 allocation is a /40 while the IPv4 announcement is a single /24.

Interesting

  • A domain named after an AS number is a naming scheme that works for any customer, and pointing this network's reverse records at someone else's version of it says who actually runs the DNS. A reader tracing an address arrives at a different organisation than the one in the routing table.
  • Marking the address family in the netname and again in the hostname is belt and braces from a network that has far more IPv6 than IPv4. The /40 could hold every address in the /24 many times over.
  • One upstream and one small block, with an allocation that size waiting behind it, is a network built for what it expects rather than what it currently carries.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
