Summary

Point Broadband

United States of America · AI-generated

fiber isp residential business

SDC-AS is operated by Point Broadband Fiber Holding, LLC.

What it's used for

  • The address space carries fiber internet services, evidenced by netnames like VB-FIBER-01, VB-FIBER-03, and PBFHL, alongside reverse DNS entries pointing to casair.net and bvunet.net.
  • With 35840 IPv4 addresses announced across 25 prefixes and only 9 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are predominantly Point Broadband Fiber Holding, LLC, though one prefix (69.59.48.0/20) is registered to Tazewell County Public Schools and another (38.88.28.0/22) to Cogent Communications, LLC.
  • The inventory consists of a mix of /20, /21, /22, /23, and /24 blocks, with the largest being four /20 prefixes, reflecting a fragmented but substantial address estate.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
