About this network

The AS handle OOOSET-AS is held by MTS PJSC.

What it's used for

• The address space carries MTS backbone and access traffic, evidenced by netnames RU-MTU and OOOSET-NET and reverse DNS entries pointing to zelenaya.net and stv.zelenaya.net.
• The AS announces 34,560 IPv4 addresses across 27 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a large-scale access and backbone network rather than a pure transit provider.
• Traffic from this AS consists of mobile subscriber eyeballs, fixed-line broadband users, and internal MTS infrastructure endpoints, consistent with MTS's role as a major Russian telecommunications operator.

Notable

• Registrants align with the announcer, listing MTS backbone NOC, MTS PJSC, and LLC Set Main Operating Center for the majority of prefixes.
• The address inventory is finely subdivided into numerous /21, /22, and /24 blocks, reflecting site-by-site segmentation typical of a large corporate and carrier estate.
• The presence of LLC Set Main Operating Center registrants on some prefixes indicates historical or operational ties to the LLC SET entity, which operates under the MTS umbrella.
