About this network

MR-SIB-MTSAS is operated by MTS PJSC, the major Russian mobile and fixed-line telecommunications provider.

What it's used for

• The address space carries consumer and mobile access traffic, evidenced by reverse DNS entries such as ppp85-140-100-0.pppoe.mtu-net.ru and host-212-109-201-0.sib.mts.ru.
• With 8192 IPv4 addresses and 20 IPv6 prefixes announced against only 7 observed neighbours, the ratio indicates an access or eyeball network rather than a transit provider.

Notable

• Registrants are consistent with the announcer, primarily listing MTS backbone NOC and MTS PJSC, with some blocks registered to MR-SIB-MTS Administration.
• The inventory is finely subdivided into 8 IPv4 prefixes, including a large /20 block (85.140.96.0/20) and several /23 blocks, reflecting site-by-site segmentation within the corporate estate.
• One prefix (185.52.140.0/23) lists Overta Internet Center as a registrant alongside MTS entities, suggesting historical or specific operational associations.
