About this network

KAORA Czech Republic is operated by Futruy s.r.o., the corporate entity behind the Kaora brand.

What it's used for

• The address space carries residential and small-business internet access, evidenced by reverse DNS entries such as admin.kaora.cz, host255.kaora.cz, and 254.98.bartanet.cz.
• The AS announces 6,400 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 84 observed neighbours, a ratio consistent with a regional access provider rather than a transit hub.
• Traffic from this AS consists of subscriber eyeballs and local business endpoints within the Czech Republic, serving the regional market identified in PeeringDB.
