INTERSVYAZ is operated by Intersvyaz LLC.

What it's used for

• The space carries residential subscriber traffic, evidenced by reverse DNS entries pointing to convex.ru (e.g., 143.5.185.64.convex.ru).
• The AS announces 256 IPv4 addresses across 1 prefix (185.5.143.0/24) with 2 observed neighbours, a ratio consistent with a local access network rather than a transit provider.
• As a regional internet service provider in Chelyabinsk, the traffic consists of subscriber eyeballs and local business endpoints.

Notable

• The RDAP registrant for the announced prefix is CSU NETWORK TEAM, which differs from the AS holder Intersvyaz LLC, indicating the address space is managed by a specific network team within the organization.
• The address inventory is a single contiguous /24 block, typical for a regional ISP managing its own customer base.
