What it's used for

• The address space carries residential fibre connectivity, evidenced by netnames UK-HAMPSTEADFIBRE-20190906 and UK-HAMPSTEADFIBRE-20220125 registered to Hampstead Fibre Ltd.
• The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 31 observed neighbours; this ratio of limited address space against a high neighbour count indicates a regional access network rather than a transit provider.

Notable

• The address inventory is compact, consisting of two /24 blocks and a single /29 IPv6 prefix, consistent with a small-scale local ISP.
