Summary

Point Broadband Fiber Holding

United States of America · AI-generated

fiber residential access isp

CUSTOM-76 is held by Point Broadband Fiber Holding, LLC.

What it's used for

  • The address space carries fiber access traffic, evidenced by the netname M-33-ACCESS-WAN assigned to nine of the ten announced IPv4 prefixes.
  • The AS announces 6656 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour; this high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants align with the announcer for the majority of the inventory, with Point Broadband Fiber Holding, LLC listed for all prefixes except 65.111.196.0/24, which is registered to Kirtland under the netname KIRTLANDWAN.
  • The address inventory is concentrated in the 65.111.192.0/22 range, consisting of four /22 blocks, four /23 blocks, and two /24 blocks, all within the United States.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
