Summary
ER-Telecom Holding
isp residential business russia
ZTELECOM-AS is operated by JSC "ER-Telecom Holding".
What it's used for
- The address space carries static business and residential access traffic, evidenced by reverse DNS entries such as
static-business.spb.ertelecom.ruand netnames likeERTH-SPB-PPPOE-17-NET. - The AS announces 301,824 IPv4 addresses across 76 prefixes with only 2 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
- Traffic consists of subscriber eyeballs and business static IPs, primarily serving the Saint Petersburg region as indicated by the
spbsubdomain in reverse DNS and the Saint Petersburg branch registrants.
Notable
- Registrants consistently identify JSC "ER-Telecom Holding" and its Saint Petersburg branch, aligning with the announcer.
- The address inventory is heavily concentrated in the 5.16.0.0/14 and 5.17.0.0/14 blocks, with additional space in 84.52.0.0/16 and 109.167.0.0/16.
- Some prefixes, such as 84.52.64.0/18 and 109.167.128.0/18, show reverse DNS for
westcall.net, indicating historical or leased space from a predecessor or partner.

Reputation
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 1,783 prefixes, as published 2026-10-17. 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.
