About this network

A mobile network of 52,992 addresses where not one of them answers to a name.

What it's used for

• The network of a Russian mobile operator. 52,992 addresses across 12 IPv4 prefixes, 38 observed BGP neighbours, and no IPv6 announced.

Notable

• Most blocks carry the netname T2RU-SUBSCRIBER-POOL-NET, repeated identically across five of them.
• Two others are RU-CELLULAR-20080103 and RU-CELLULAR-20120926.
• The registry lookup for 46.237.40.0/22 failed, so nothing here describes that block's record.
• The AS handle is MCC T2 Russia Network.
• Eighteen addresses were sampled and none returned a name.

Interesting

• Another mobile carrier in this same range answers fifteen of eighteen sampled addresses with names that declare whether the subscriber is behind carrier NAT, on ordinary mobile internet, or on a static address. This one answers none. Both operate the same kind of network at a similar scale, and the difference is entirely a decision about whether the outside world should be able to tell anything about traffic coming from you.
• Publishing subscriber classification helps receiving networks handle mobile traffic sensibly. Withholding it makes the whole range opaque. Neither is wrong, but the choice is visible in the data.
• SUBSCRIBER-POOL-NET names the function rather than the location or the batch, and the same netname on five separate blocks means the registry has no way to tell them apart. Whoever maintains this uses a template and does not treat netnames as an identifier.
• No IPv6 at all from a mobile network, where it is usually deployed earliest.
