Summary

Highlands Cable Group

United States of America · AI-generated

cable residential access isp

The AS handle HIGHLANDS-CABLE is held by Highlands Cable Group.

What it's used for

  • The address space carries residential cable access traffic, evidenced by reverse DNS entries like dhcp-173-246-218-128.res.highlandscable.net and netnames HIGHLANDS-CABLE and HIGHLANDS-CABLE-GROUP.
  • The AS announces 4096 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants are consistent with the announcer, with Highlands Cable Group listed for three prefixes and Optimum Online for the prefix 173.246.220.0/23, which may reflect historical acquisition or leased space.
  • The inventory consists of four IPv4 prefixes totaling 4096 addresses, with no IPv6 prefixes announced.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
