About this network

NTK is the autonomous system for Novotelecom Ltd, a telecommunications provider based in Novosibirsk.

What it's used for

• The address space carries residential and business broadband traffic, evidenced by reverse DNS entries like l37-193-0-0.novotelecom.ru and l5-128-64-0.novotelecom.ru.
• With 566272 IPv4 addresses announced across 61 prefixes and 24 observed neighbours, the ratio indicates an access network serving end-users rather than a transit provider.

Notable
