Summary

Chelyabinsk-Signal

Russian Federation · AI-generated

isp residential russia

CHELYABINSK-SIGNAL-AS is operated by Chelyabinsk-Signal LLC.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries such as chelsignal.ru, profitserver.net, and ispsystem.net.
  • The AS announces 5632 IPv4 addresses across 8 prefixes and 4 IPv6 prefixes, with 7 observed neighbours, indicating a regional access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for the Chelyabinsk region, consistent with the operator's role as a local internet service provider.

Notable

  • Registrants include both Chelyabinsk-Signal LLC and PDK LLC, with netnames like CHELYABINSK-SIGNAL-NET and RU-PDKLLC-20110421 appearing across the inventory.
  • The address inventory is finely subdivided into /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a regional ISP.

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 1,781 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.
