About this network

Every address in the sample answers with the same name, and that name says the address is not in use.

What it's used for

• A distribution company's network. A single IPv4 prefix announced from Germany, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.

Notable

• All three queried addresses answered, and all three gave the identical name: two letters for an address, a hyphen, and a phrase declaring the address unused, on the company's own domain.
• That phrase is written with a capital in the middle of the word, so it was typed by hand into a zone file rather than produced by a generator.
• The same name for every address means the zone maps the whole range to one label, which is a wildcard record rather than a set of individual entries.
• The netname is the brand plus the word for a network, and the block is registered to the company with a role for abuse.

Interesting

• Declaring a range unused in its own reverse names is a genuinely useful signal. Mail systems and log readers can tell at a glance that nothing is supposed to be answering there, which makes anything that does answer worth a second look.
• A wildcard reverse record is the least effort that still produces an answer, and it is the reason the same string appears at three addresses that have nothing else in common.
