About this network

The largest block is registered to an individual, not to the company that announces it.

What it's used for

• An information technology services and integration company. Fourteen IPv4 prefixes and one IPv6 /48 announced from Germany, seventy-six thousand addresses, through two observed BGP neighbours.

Notable

• The /16 that holds most of this network's address space lists a single registrant, a person's name, with no company and no abuse role beside it.
• The other thirteen blocks are fragments of one range, in five sizes from /21 down to /24, with gaps between them.
• Eight of those carry a netname with the country code, an old company code and a six-digit date from the nineties; the rest use short numbered names with no date at all.
• The registrant on the dated blocks is one company trading as another, with two corporate forms and an ampersand in a single field.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A person named as sole registrant on sixty-five thousand addresses is a record from an era when address space was granted to whoever asked. It has outlived the process that created it.
• The six-digit date, two digits for the year, is from before four-digit years became standard practice in these fields, which dates the allocation more precisely than the block itself does.
• Fourteen routes for one company, with two upstreams and nothing published in reverse, is address space held rather than operated.
