About this network

UFA-AS is operated by JSC "ER-Telecom Holding".

What it's used for

• The address space carries residential and business subscriber traffic, evidenced by netnames such as ERTH-UFA-PPPOE-24-NET and reverse DNS entries like dynamicip-176-213-232-0.pppoe.ufa.ertelecom.ru and static-business.ufa.ertelecom.ru.
• The AS announces 40,192 IPv4 addresses across 18 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio characteristic of a local access network rather than a transit provider.
• Traffic consists of broadband subscriber eyeballs and small business endpoints within the Ufa region, delivered via PPPoE and dynamic IP allocation.

Notable

• All registrants align with the announcer, consistently listing JSC "ER-Telecom Holding" or its Ufa Branch.
• The inventory is dominated by /21 and /20 blocks, with a single larger /19 prefix, reflecting a segmented allocation for different service tiers or geographic sub-areas within the Ufa network.
