About this network

Reverse names containing the letters in-addr.arpa, one of them ending in .db.

What it's used for

• A hosting provider registered in Canada announcing mostly European address space. 4,608 addresses across 10 IPv4 prefixes, six IPv6 prefixes, and a single observed BGP neighbour.

Notable

• Netnames span CA-BLACKHOST- dated 19940812, 19981229, 20050512 and 20190430, plus a bare BlackHOST and one UK-PINGTECHNOLOGYLABS-20040723 registered to another company.
• Ten of eighteen sampled addresses returned names, most of the form black.host-254.30.54.86.in-addr.arpa.
• Two end in .db: black.host-128.140.104.212.in-addr.arpa.db.
• One is scanner-info.rootevidence.com.
• The AS handle is BLACKHOST AS12989.NET.

Interesting

• Those hostnames should not exist. in-addr.arpa is the internal suffix of a reverse lookup, not something that belongs inside the answer, and .db is the file extension of a zone file. Somebody built the reverse zone with a template that pasted the full query name and, in two cases, the filename of the zone itself into the record. It has been serving that way to anyone who looks.
• Netnames dated 1994 and 2019 in one small inventory, with blocks in ranges allocated twenty-five years apart. Hosting providers assemble space from wherever it can be bought, so the registry dates map the acquisition history rather than the company's age.
• One neighbour for a provider with sixteen announcements is unusual and worth noting, since everything advertised here depends on a single relationship.
• A block registered to an unrelated UK company sits in the middle of the inventory.
