Summary
Comfortel
isp residential russia st-petersburg
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.proand netnames likeCOMFORTEL-NETandUUT-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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,782 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
