About this network

SUTTK-AS is operated by Joint Stock Company TransTeleCom.

What it's used for

• The address space carries residential and mobile access traffic, evidenced by netnames such as SUTTK-ORB-PPPoE and SUTTK-CHEL-Dynamic, and reverse DNS records pointing to in-addr.suttk.ru.
• The AS announces 24,064 IPv4 addresses across 43 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours; this high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants for the largest prefixes consistently identify the holder as TTC NOC; Joint Stock Company TransTeleCom or SUTTK NOC; TTC NOC, aligning with the AS holder.
• The address inventory is finely subdivided into numerous /22, /23, and /24 blocks, reflecting internal segmentation for different service regions or technologies within the corporate estate.
