About this network

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.
