AS12610 — ASNETBASE

AS12610 announces 1 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

One /21, unchanged since November 1999, with no IPv6 at all.

What it's used for

• Business connectivity and hosting in Germany. 2,048 addresses in a single IPv4 prefix, two observed BGP neighbours, and no IPv6 announced.

Notable

• The entire inventory is 213.214.24.0/21, netname DE-ROCKENSTEIN-991101.
• The registry contact is rockenstein AG - technical contacts / NOC, spelling the company name in lower case where the holder field spells it with a capital.
• The AS handle is ASNETBASE, a third name again.
• Three sampled addresses were queried and none returned a name.

Interesting

• One block, one netname, one date, and nothing added in twenty-seven years. Networks that never came back for more space are as informative as the ones that did: a /21 was enough, and the company grew in ways that did not need addresses.
• No IPv6 whatsoever puts this in a shrinking minority. Every other German network in this stretch of the number range announces at least a /32, usually obtained long after their IPv4. Not having taken one is a decision that gets more expensive to reverse each year, since the parts of the Internet that are IPv6-only keep growing.
• The capitalisation disagreement inside a single registry record is the small kind of drift that accumulates in any database edited by hand over decades. Nothing validates it, so both spellings are equally official.
