About this network

The AS handle CITYLINK-AS is held by CityLink Ltd.

What it's used for

• The address space carries residential and business internet access, evidenced by reverse DNS entries such as ip-94-140-247-254.citylink.pro and netnames like CL and RU-CITYLINK-20100525.
• The network announces 19 IPv4 prefixes covering 19712 addresses and maintains 39 observed neighbours, a ratio consistent with an access provider distributing traffic to end-users rather than a transit hub.
• Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the Petrozavodsk region, as indicated by the operator's registration address and PeeringDB classification as a Cable/DSL/ISP.

Notable

• One prefix, 176.97.108.0/23, is registered to M Svyaz LLC with the netname RU-MSVYAZ-20110923, indicating a distinct ownership or leasing arrangement within the announced space.
