AS15672 announces 11 IPv4 prefixes covering 18,432 addresses and 1 IPv6 prefixes.

About this network

The AS handle is not a name. It is a routing instruction with a coverage disclaimer attached.

What it's used for

• A regional provider's network. Fifteen IPv4 prefixes and one IPv6 prefix announced from the Russian Federation, eighteen thousand six hundred and eighty-eight addresses, across forty-eight observed BGP neighbours.

Notable

• After the company abbreviation, the handle instructs the reader to advertise with the no-export community, states that this is not available in all areas, and ends with a letter and a digit.
• The fifteen blocks use four different netname conventions at once: a country code with an allocation date on eight of them, a longer form naming a city on two, that same form without the city on one, and a bare abbreviation on the last.
• Every block's registrant begins with the registry's own name before the company's.
• The company itself is named on most blocks but is missing from the three that use the longer netname form.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A community is a tag attached to a route that asks the receiving network to treat it a certain way. Putting that request in the handle means it reaches anyone reading the registry and no router at all, which is the wrong place for it by one whole layer.
• Four netname conventions across fifteen blocks is what a decade of separate allocations looks like when nobody goes back to normalise the earlier ones.
