AS15683 DOMASHKA-AS

The holder's legal name is another autonomous system's number, quotation marks included.

What it's used for

• A consumer broadband provider. Eight IPv4 prefixes and one IPv6 prefix announced from Ukraine, twenty-four thousand addresses, through a single observed BGP neighbour.

Notable

• The registered company name is the letters AS followed by a four-digit number, in quotes, then the words for a limited liability company. That number is not this one.
• Every readable block carries a netname built from a country code and a four-letter abbreviation that matches neither the company name nor the trading brand, half of them with an allocation date.
• All eighteen sampled addresses answer, across two different domains.
• The names label the structure of each subnet: the network address is prefixed subnet-, the broadcast address bcast-, and both carry an equipment name such as titan or vega.
• Some addresses are named empty- and answer anyway, so the zone says they are unused.
• Pool names are the third octet zero-padded to three digits, except one that runs to four.
• The largest block's registry lookup failed, so its details are unknown rather than absent.

Interesting

• Naming the network and broadcast addresses of every subnet in public DNS hands a reader the exact boundaries of the internal layout, subnet by subnet, without a single probe.
• A company named after an autonomous system number, holding a different one, is the kind of thing a registry will never resolve. Both records are correct and neither is legible.
