About this network

The AS handle contains this network's own AS number, digits included.

What it's used for

• A hosting and colocation provider. Forty-three IPv4 prefixes and ten IPv6 prefixes announced from Germany, one hundred and forty-three thousand addresses, across one hundred and twenty-two observed BGP neighbours.

Notable

• The AS handle is a three-letter brand joined to the number of the AS itself, so the identifier repeats inside its own name.
• Every documented netname carries the same retired brand and an allocation date, never the current company name.
• The first registrant on each block is a lowercase role naming that brand and its registry status.
• Two large ranges are each announced as one half plus a stack of smaller pieces covering the other half, turning two routes into more than twenty.
• One answering address names a router, a virtual datacentre and a city site code under a colocation domain; the other names an interface and a firewall on a customer's domain, in capitals.
• Eighteen addresses were queried for reverse DNS and two returned a name.

Interesting

• A firewall interface named in public DNS is a free hint about where a customer's boundary sits, and it comes from a naming habit rather than any decision to publish it.
• Putting the AS number in the handle is redundant but useful in practice, since the handle is what appears in tooling that has already lost the number.
• One brand across forty-three netnames, none updated after the company changed hands, is the normal outcome. Renaming address blocks buys nothing and risks breaking references.
