About this network

The AS handle HNMS-AS is held by the Hellenic National Meteorological Service.

What it's used for

• The address space carries infrastructure for the national meteorological agency, identified by the netname HNMS and registrant HNMS NOC on both announced IPv4 prefixes.
• The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained government network rather than a transit or access provider.

Notable

• The registrants for both IPv4 prefixes are HNMS NOC, which aligns directly with the AS holder name Hellenic National Meteorological Service.
• The address inventory consists of two contiguous IPv4 blocks (195.251.244.0/23 and 195.251.246.0/24) and a single IPv6 /47, reflecting a modest internal estate typical of a specialized government agency.
