About this network

The AS handle INTERFIBER- is held by Interfiber Networks LDA.

What it's used for

• The address space carries a mix of leased and owned infrastructure, evidenced by netnames COGENT-EUROPEAN-OPERATIONS-001 (Cogent Communications, LLC), UP-COLO, and PT-INTERFIBER-20210422 (Interfiber Networks LDA).
• With 1,536 IPv4 addresses and 1 IPv6 prefix announced against 119 observed neighbours, the high neighbour-to-address ratio indicates a transit or network service provider role rather than an access network.
• As a Network Service Provider (NSP) based in Portugal, the traffic consists of upstream transit and interconnection for its customer base.

Notable

• Registrants do not uniformly match the announcer; the largest prefix is registered to Cogent Communications, LLC, while the smallest is registered to Interfiber Networks LDA.
• The address inventory is small and fragmented, consisting of three distinct IPv4 prefixes and one IPv6 prefix.
