Summary

HNS

United Kingdom · AI-generated

business connectivity managed-services

HNS is operated by SysGroup plc.

What it's used for

  • The address space carries business connectivity and managed IT services, evidenced by netnames such as UK-SYSGROUP-19970903 and UK-INSTILLER-20150618, and reverse DNS entries like 87-237.67-255.hns.net and rockford-it.net.
  • The AS announces 23,296 IPv4 addresses across 21 prefixes and 3 IPv6 prefixes, while maintaining 72 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a role focused on business connectivity and network interconnection rather than mass residential access.
  • Traffic from this AS consists of business connectivity, cloud connections (including Azure and AWS), and managed IT services for clients in sectors such as healthcare, legal, and manufacturing.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to SysGroup plc under the SYSGROUP-RIPE-DB-MAINTAINERS maintainer, though one prefix (185.105.64.0/22) is registered to Instiller Limited.
  • SysGroup plc acquired 100% of Hub Network Services Limited (HNS), the original holder of this AS, integrating it into their managed services portfolio.
  • The inventory includes a mix of /20, /21, /22, /23, and /24 prefixes, with the largest block being 195.94.112.0/20.

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 1,773 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.
