AS15925 announces 4 IPv4 prefixes covering 11,264 addresses and 1 IPv6 prefixes.

About this network

Nine of eleven answering addresses return a name that says there is no name.

What it's used for

• A provider's network. Four IPv4 prefixes and one IPv6 /29 announced from Germany, eleven thousand two hundred and sixty-four addresses, across eighty-five observed BGP neighbours.

Notable

• Eleven of twelve queried addresses answered. Nine returned the same wildcard name, whose first label is a hyphenated declaration that no reverse name exists for the address.
• The other two are six-digit customer numbers on the same brand under a different top-level domain, so the placeholder and the real names live in separate zones.
• There is no holder name in the routing record, only the handle.
• Two blocks carry a netname built from a second company's brand while their registrant is the first; the other two carry a country code, a phrase about access, and a date, with the second company as registrant. The two names are swapped between the two families.
• The IPv6 allocation is a /29, the size given to a provider to hand out.

Interesting

• A wildcard saying that no name exists is the most informative empty answer in this range. A missing record and a record that says nothing look identical to a person reading logs, but they behave differently: one takes a full delegation walk to fail, the other answers immediately.
• Eighty-five neighbours on eleven thousand addresses is an exchange participant peering far more widely than its own traffic would require.
