About this network

The AS handle STC-AS is held by PJSC Rostelecom.

What it's used for

• The address space carries residential access traffic, evidenced by the reverse DNS entry 62.183.15.255.modem-pool.kuban.ru and netnames such as MacroregionalSouth and RADNET.
• With 119040 IPv4 addresses announced across 74 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants for the largest prefixes include PJSC Rostelecom and STC Internet Center, both associated with the Rostelecom technical team, confirming alignment with the announcer.
• The address inventory is finely subdivided into numerous /21 and /22 blocks, consistent with site-by-site segmentation within a large corporate estate.
• The AS was first seen in RIS in 2003, indicating a long-standing presence in the routing table.
