About this network

WOSACZ-AS is operated by H-data, spol. s r.o.

What it's used for

• The address space carries static router infrastructure, evidenced by reverse DNS entries such as 81.19.12.128.static.router.wosa.cz and netnames like CZ-HDATA-20160205 and WOSA-CZ.
• The AS announces 2048 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio indicative of a small-scale access or business network rather than a transit provider.

Notable

• Registrants for the announced prefixes include both H-data, spol. s r.o. and FASTER CZ spol. s r.o., with the latter appearing as the technical contact for three of the four IPv4 blocks.
• The inventory consists of four distinct IPv4 prefixes ranging from a /22 to /24s, alongside a single IPv6 /29, reflecting a modest and segmented address estate.
