Summary

ER-Telecom Holding

Russian Federation · AI-generated

residential isp ural russia

EKAT-AS is operated by JSC "ER-Telecom Holding".

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS names such as dynamic.ekat.ertelecom.ru, static-business.ekat.ertelecom.ru, and akado-ural.ru.
  • The AS announces 143,616 IPv4 addresses across 66 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic consists of subscriber eyeballs and business static IPs for the Ural region, specifically Yekaterinburg, as indicated by the ekat subdomain in the reverse DNS records.

Notable

  • All registrants in the sample are JSC "ER-Telecom Holding" or its Yekaterinburg Branch, consistent with the AS holder.
  • The inventory is finely subdivided into numerous /20 and /21 blocks, reflecting site-by-site segmentation for a large regional ISP.
  • The presence of akado-ural.ru in the reverse DNS indicates the operation of the Akado brand, a subsidiary or service line of ER-Telecom.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
