What it's used for

• The address space carries residential broadband traffic, evidenced by netnames such as ERTH-IRKUTSK-PPPOE-13-NET and ERTH-IRKUTSK-PPPOE-NET, and reverse DNS entries like 5x167x20x0.dynamic.irkutsk.ertelecom.ru and 84-244-36-0.pppoe.irknet.ru.
• The AS announces 73,216 IPv4 addresses across 49 prefixes and 10 IPv6 prefixes, while maintaining only 2 observed neighbours, a ratio characteristic of an access network serving end-users rather than a transit provider.
