AS15227 announces 28 IPv4 prefixes covering 115,200 addresses and 0 IPv6 prefixes.

About this network

Every reverse name declares the address unassigned, under a carrier that no longer exists.

What it's used for

• A regional fibre carrier. Twenty-eight IPv4 prefixes announced from the United States, no IPv6, and a hundred and fifteen thousand addresses.

Notable

• Sixteen of eighteen sampled addresses answered, and every one of them writes the address into the host label followed by the word unassigned, under the domain of a predecessor carrier.
• Most netnames are the company name, a two-letter marker and a counter, running through a numbered series with gaps in it.
• One announced block is registered to the regional internet registry itself rather than to any company, under a netname that is just the word for network and the first octet.
• Another carries the UU- prefix of a long-retired carrier and is registered to a fibre company in a different state.
• One observed BGP neighbour carries all twenty-eight prefixes.

Interesting

• A reverse zone that answers for every address and labels each one unassigned is a wildcard covering space the carrier has not allocated to customers. It is honest, and it is also a free inventory: a scanner learns which addresses are unused without sending a single packet to them.
• The registry itself appearing as a registrant marks space held or reclaimed centrally, which is unusual to see inside an operating carrier's announcements.
• A numbered netname series with gaps is a record of assignments that were returned or transferred. The missing numbers are as informative as the present ones.
