Summary

ER-Telecom Holding (Tula)

Russian Federation · AI-generated

isp residential business tula

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

What it's used for

  • The address space carries subscriber traffic for the Tula region, with reverse DNS entries showing dynamic.tula.ertelecom.ru, pppoe.tula.ertelecom.ru, and static-business.tula.ertelecom.ru.
  • The AS announces 49,664 IPv4 addresses across 25 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio indicative of an access network rather than a transit provider.
  • Traffic consists of residential broadband subscribers and business static IP customers served by the Tula branch of ER-Telecom.

Notable

  • Registrants for all sampled prefixes are consistent with the announcer, listing JSC "ER-Telecom Holding" and its Tula Branch.
  • The inventory is dominated by /20 and /21 blocks in the 176.212.0.0/16 and 176.213.0.0/16 ranges, alongside smaller /22 and /24 allocations in 5.0.0.0/8, 46.0.0.0/8, 92.0.0.0/8, 109.0.0.0/8, and 188.0.0.0/8.

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 1,772 prefixes, as published 2026-10-15. 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.
