About this network

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.

• The inventory includes a mix of /20, /21, /22, /23, and /24 prefixes, with the largest block being 195.94.112.0/20.
