AS12637 — SEEWEB Web hosting, colocation and cloud services
Network type: hosting
AS12637 announces 27 IPv4 prefixes covering 79,360 addresses and 10 IPv6 prefixes.
About this network
1,055 BGP neighbours, the most of any network in this sweep, and five separate full-size IPv6 allocations.
What it's used for
- Web hosting, colocation and cloud services. 81,408 addresses in 35 IPv4 prefixes, 10 IPv6 prefixes, and 1,055 observed BGP neighbours.
Notable
- Netnames run from IT-SEEWEB-19980908 and IT-SEEWEB-19990412 through 2000, 2001, 2005, 2009, 2010, 2011 and IT-SEEWEB-20120712.
- One block breaks the pattern: 176.56.128.0/21, netname EE-128BIT-20110530, an Estonian registration.
- The IPv6 side holds five /29s — 2001:4b78::, 2a04:2700::, 2a05:be80::, 2a0b:fd40:: and 2a0d:b000:: — plus a /31 and four /32s.
- One sampled address of eighteen answered, as pop3.f2.net.
Interesting
- Over a thousand neighbours puts this network among the most connected in the number range, and it gets there on 81,000 addresses. Hosting companies peer with everyone they can, because every network they reach directly is traffic that costs them nothing and arrives faster.
- Five separate /29s is five full registry allocations. Nobody is granted that many by asking; they arrive attached to companies that were bought, each bringing its own membership and its own space. The IPv6 inventory is a list of acquisitions in a way the IPv4 inventory is not.
- An Estonian netname inside an Italian hosting inventory is the address market at work, and pop3.f2.net names a mail protocol on a brand that appears nowhere else in the record.
