residential isp cable dsl

NCNET-AS is operated by PJSC Rostelecom, formerly known as National Cable Networks (NCNET).

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as broadband-5-228-64-0.ip.moscow.rt.ru and broadband-37-204-64-0.ip.moscow.rt.ru.
  • With 512,768 IPv4 addresses announced across 23 prefixes and only 11 observed neighbours, the high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
  • Traffic consists of subscriber eyeballs for cable and DSL services in the Moscow region, consistent with Rostelecom's role as a major Russian telecommunications operator.

Notable

  • Registrants for all sampled prefixes are consistent with the announcer, listing NCNET NCC Operations, PJSC Rostelecom, and PJSC Rostelecom Technical Team.
  • The operator was formerly known as National Cable Networks (NCNET), which was acquired by Rostelecom; the AS handle retains the legacy NCNET-AS name.
  • The inventory is dominated by large /16 and /17 blocks, with a single IPv6 prefix 2a02:2168::/29 announced.

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 1,779 prefixes, as published 2026-10-21. 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.
