Summary
Central Telegraph (QWERTY)
isp eyeball legacy
CNT-AS — Central Telegraph (Центральный телеграф), a Moscow telecom operator whose consumer internet and IPTV service is sold under the QWERTY brand. The AS carries that subscriber network.
What it's used for
- Home broadband in Moscow and the surrounding region. Roughly 260,000 IPv4 addresses across nine prefixes — several full /16s and /17s — with about a dozen BGP neighbours.
- The subscriber space resolves to
host-IP-DASHED.qwerty.ruthroughout: a flat, generated naming scheme covering the77.41,79.164and79.165blocks. That is eyeball addressing, one PTR per customer address. - Some older blocks (
212.13.96.0/19,212.15.96.0/19) carry no useful rDNS at all, returning only the raw classless-delegation names.
Notable
- The holder's name is a trap in the other direction: Central Telegraph sounds like a state telegraphy institution, and historically it was one — the Moscow central telegraph office. Today the AS is an ordinary consumer ISP, and the rDNS is what settles it.
- The QWERTY brand does not appear in the registry object anywhere. Only the rDNS connects the legal holder to the retail service.
Interesting
- Central Telegraph's building on Tverskaya Street is a Moscow landmark, and the company is one of the oldest continuously operating communications businesses in Russia. Its AS number now carries residential internet rather than telegrams.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,784 prefixes, as published 2026-10-19. 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.
