About this network

BNET-INTERNET is operated by Core4Net, s.r.o.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to bnet-internet.cz and wlanet.cz, and netnames such as CZ-CORE4NET-20101008 and BNET-INFRASTRUCTURE.
• The AS announces 5376 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 29 observed neighbours; this ratio of moderate address space against a significant number of peering partners indicates a regional access provider rather than a pure transit hub.
• Traffic consists of subscriber eyeballs for cable and DSL customers in the Czech Republic, as Core4Net operates a shared backbone and access network for local ISPs.

Notable

• Registrants for the largest prefixes are BNET Business, s.r.o. Hostmaster and Core4Net, s.r.o., which align with the AS holder, while the smallest prefix lists Wlanet system s.r.o. Hostmaster.
• The address inventory is subdivided into three distinct IPv4 blocks, with the largest being a /20 and the smallest a /24, reflecting a segmented corporate and access estate.
