About this network

AS50187 is operated by BaikalWestCom, a regional telecommunications provider in the Russian Federation.

What it's used for

• The address space carries mobile and broadband access traffic, evidenced by reverse DNS entries such as pppoe.hi-link.ru and ip.newbwc.ru, and netnames including RU-HI-LINK-20171130 and BaikalWestCom.
• The AS announces 5376 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, while maintaining 22 observed neighbours; this ratio of moderate address inventory to a significant number of peering partners indicates a regional access network rather than a pure transit provider.
• Traffic from this AS consists primarily of subscriber eyeballs and mobile data sessions for customers in the Irkutsk region and surrounding areas, consistent with the operator's history as a mobile and fixed-line ISP.

Notable

• Registrants for the announced prefixes are predominantly HiLink LLC and BaikalWestCom Ltd, with some entries listing HILINK ltd; these entities are associated with the operator's historical branding and corporate structure.
• BaikalWestCom was transferred to the control of Tele2 Russia as part of a 2014 amalgamation involving Rostelecom's wireless assets, leading to a rebranding of the service.
• The inventory includes a mix of /22 and /23 blocks, with the largest being 37.139.80.0/22, 185.234.228.0/22, and 212.67.28.0/22.
