AS15699 — AS_ADAM Adam Datacenter

Network type: hosting

AS15699 announces 16 IPv4 prefixes covering 27,904 addresses and 5 IPv6 prefixes.

About this network

Five IPv6 allocations from five different ranges, and an underscore in the AS handle.

What it's used for

• A data centre operator. Sixteen IPv4 prefixes and five IPv6 prefixes announced from Spain, twenty-seven thousand addresses, across forty-four observed BGP neighbours.

Notable

• The AS handle joins the word for autonomous system to the brand with an underscore, then adds a description of the business.
• The five IPv6 blocks come from five unrelated ranges rather than one allocation split up, which means five separate requests over five separate periods.
• Ten blocks carry the operator's own netname, built from a country code, the company name with its legal form folded in, and an allocation date, with dates spread over a decade.
• Four blocks belong to three other companies entirely, two of them sharing a single netname and a single date.
• The holder name ends its legal form without the final full stop, and the netnames keep that form as two letters.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Five IPv6 allocations is more remarkable than a large one. A network gets a second only by asking again, so five is either five acquisitions or five occasions when asking was easier than reorganising what was already held.
• A data centre with no reverse names at all, on twenty-seven thousand addresses, hands nothing to anyone scanning it. Everything customer-facing lives in forward DNS the operator does not control.
