About this network

The AS handle COMFORTEL is held by Comfortel Ltd., a regional internet service provider based in St. Petersburg, Russia.

What it's used for

• The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries such as 85-142-90-0.customer.comfortel.pro and netnames like COMFORTEL-NET and UUT-NET.
• With 43,520 IPv4 addresses announced across 62 prefixes and 124 observed neighbours, the high neighbour-to-address ratio indicates a regional access network rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs and local business endpoints within the St. Petersburg region, consistent with Comfortel's role as a regional ISP.

Notable

• Registrants largely align with the announcer, with most prefixes registered to Comfortel Ltd. or Comfortel Ltd Contacts Data; one prefix (85.143.160.0/21) is registered to the Scientific Research Institute for System Analysis of the National Research Centre "Kurchatov Institute".
• The address inventory is finely subdivided into numerous /21 and /22 blocks, reflecting site-by-site segmentation typical of a regional access provider managing distinct customer segments.
