AS213704 — RU-SHARK-U

AS213704 announces 1 IPv4 prefixes covering 256 addresses and 3 IPv6 prefixes.

About this network

The AS handle RU-SHARK-U is held by Shark Telecom LLC.

What it's used for

• The space carries a single IPv4 block with netname RU-SHARK-13 and three IPv6 prefixes under the 2a03:9000::/32 range.
• With 256 IPv4 addresses and 3 IPv6 prefixes announced against only 2 observed neighbours, the inventory suggests a small-scale access or internal corporate network rather than a transit provider.
• Traffic from this AS consists of office workers and internal endpoints for the Moscow-based operator, given its registered address in Mitino, Moscow.

Notable

• The RDAP registrant for the announced IPv4 prefix is listed as Abuse-C Role, which is a generic abuse contact role rather than a distinct corporate entity, consistent with the holder Shark Telecom LLC.
• The address inventory is minimal, consisting of one /24 IPv4 block and three /40 IPv6 prefixes, indicating a tightly scoped operational footprint.
