AS12586 — ASGHOSTNET GHOSTnet GmbH

Network type: hosting

AS12586 announces 230 IPv4 prefixes covering 140,032 addresses and 29 IPv6 prefixes.

About this network

301 IPv4 announcements for 150,016 addresses, four separate IPv6 allocations, and a placeholder published in public DNS.

What it's used for

• Hosting and connectivity in Germany. 150,016 addresses in 301 IPv4 prefixes, 38 IPv6 prefixes, and 59 observed BGP neighbours.

Notable

• The blocks are split fine: 301 announcements average under 500 addresses each, and the listed prefixes are mostly /22s out of 5.230.0.0 and 5.175.0.0.
• Netnames run DE-GHOSTNET-20080918, DE-GHOSTNET-20120802 and DE-GHOSTNET-20120911.
• One block in the middle of the inventory is DE-Ackermann-IT, registered to a named individual, Sascha Ackermann.
• Four of the IPv6 announcements are separate /29s: 2a00:12d8::/29, 2a00:19d0::/29, 2a01:bd40::/29 and 2a02:7a0::/29.
• One sampled address answers placeholder.noez.de.
• First seen in routing data in June 2002, a real date rather than the floor of the archive.

Interesting

• A /29 is a full registry allocation to a member, and holding four of them means being four members, or having absorbed three others. IPv6 blocks are the clearest fossil record of corporate acquisition available, because nobody bothers to consolidate address space that costs nothing to keep.
• placeholder.noez.de is exactly what it says: a name filled in so the field would not be empty, published to the world and still answering. Reverse DNS is the one part of a network where temporary decisions become permanent in public.
• Five further announcements subdivide a single /44 into pieces of four different sizes, which is the shape of address space handed out to customers one request at a time.
