About this network

INFTELE-AS is operated by Infinity Telecom, s.r.o., a licensed telecom operator based in Prague, Czech Republic.

What it's used for

• The address space carries a mix of Infinity Telecom's own infrastructure and leased blocks, with netnames including CZ-INFTELE-20181112, CZ-INFTELE-20190329, and IN8INITY-HOSTING-SERVICES-CZ, alongside Cogent Communications blocks COGENT-149-7-16 and COGENT-154-57-16.
• The AS announces 6,400 IPv4 addresses across 12 prefixes and 9 IPv6 prefixes, while maintaining 187 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large access network.
• As a licensed telecom operator engaged in traffic exchange with partners worldwide, the traffic from this AS consists of wholesale transit, peering, and hosting services for business clients.

Notable

• Registrants largely align with the announcer, with most prefixes registered to Infinity Telecom NOC or Infinity Telecom, s.r.o., though two /22 blocks are registered to Cogent Communications, LLC and one /24 to Like Media s.r.o.
• The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, reflecting a segmented corporate and service estate rather than a single contiguous allocation.
