What it's used for

• The address space carries residential broadband traffic, evidenced by netnames such as ERTH-BRYANSK-DYNAMIC-PPPOE-NET and ERTH-BRYANSK-PPPOE-5-NET, and reverse DNS entries like 178x75x16x0.dynamic.bryansk.ertelecom.ru and 109x194x7x255.static-customer.bryansk.ertelecom.ru.
• The AS announces 81,152 IPv4 addresses across 45 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio characteristic of an access network rather than a transit provider.
• Traffic consists of subscriber eyeballs for residential internet and television services in the Bryansk region, as indicated by the bks-tv.ru reverse DNS records and the operator's status as a regional ISP.

Notable
