Unclassified APNIC
Summary
Highland Communication Services
municipal government network
The AS handle HCS is held by Highland Communication Services.
What it's used for
- The address space carries municipal network operations, evidenced by the netname
CITY-OF-HIGHLANDassigned to all three announced prefixes. - The inventory consists of 4096 IPv4 addresses across 3 prefixes, with a single observed neighbour, indicating a self-contained internal network rather than a transit or large-scale access provider.
Notable
- All registrants align with the announcer, consistently listed as Highland Communication Services.
- The address inventory is finely subdivided into three contiguous blocks within the 107.182.64.0/21 range, reflecting site-by-site segmentation typical of a corporate or municipal estate.

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 1,778 prefixes, as published 2026-10-20. 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.
