isp hosting legacy

A small US network carrying amateur radio infrastructure alongside its own address space.

What it's used for

  • Announcing space on behalf of several separate organisations. 2,304 IPv4 addresses over seven prefixes with one observed BGP neighbour, plus twenty IPv6 announcements.

Notable

  • Two of the blocks are registered as AMPRNET to Amateur Radio Digital Communications — part of 44.0.0.0/8, the range handed to amateur packet radio in the 1980s and still administered for amateur use today.
  • Two more belong to Tampa Co-Op, under the netnames TAMPA-NET-01 and GCEH-2025.
  • Reverse DNS names the projects rather than the provider: tampa.coop, pttlink.org — the PTTLink repeater linking network — and w9cr.net, an amateur radio callsign used as a domain name.
  • The IPv6 announcements descend through 2602:2af:101::/48, 102::/47, 104::/46, 108::/45, 110::/44, 120::/43, 140::/42 and 180::/41, each rung twice the size of the one before.

Interesting

  • That IPv6 staircase is what a single contiguous range looks like when it is written out as CIDR blocks instead of one aligned prefix. Nobody designs an address plan in that shape; it falls out of expressing "everything from here to there" in a routing table.
  • 44.0.0.0/8 is one of the odder survivals in the address registry: a whole class A given to hobbyists in 1981, kept in amateur hands for four decades, with a portion sold in 2019 to fund grants for amateur radio and networking work. Space from it turning up under one small AS, next to a repeater linking network and a callsign domain, is the block being used for exactly what it was set aside for.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,773 prefixes, as published 2026-10-13. 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.
