AS12552 — GlobalConnect-AS12552 GlobalConnect AB

AS12552 announces 197 IPv4 prefixes covering 558,592 addresses and 39 IPv6 prefixes.

About this network

948 BGP neighbours, 298 IPv4 prefixes, and reverse names with in-addr left visible inside them.

What it's used for

• Nordic backbone and transit. 553,984 addresses in 298 IPv4 prefixes, 64 IPv6 prefixes, and 948 observed BGP neighbours.

Notable

• The AS handle is IPO-EU, while the registry holder is GlobalConnect AB and the registrant on most blocks reads IP-ONLY Registry.
• Netnames run from SE-GLOBALCONNECT-990914 through the 2000s to 20081119 — a decade of allocations under one name.
• A separate family, SE-DGCSYSTEMS-20021203 and SE-DGCSYSTEMS-20040322, is registered to DGC Systems and Iver Sverige AB.
• 137.133.128.0/17 is netname ABB, registered to ABB GTO Network Tower.
• Two sampled addresses answer 255.191.241.83.in-addr.dgcsystems.net and 254.223.241.83.in-addr.dgcsystems.net.

Interesting

• Those reverse names have the machinery showing. 83.241.191.255 reversed is 255.191.241.83, which belongs in front of in-addr.arpa; here the whole construction has been grafted onto a company domain instead, so the label in-addr survives in a name that is otherwise ordinary. It is the plumbing of reverse DNS appearing in its own output.
• 948 neighbours is the number that defines this network. Almost a thousand adjacencies is not a customer base, it is a position — the AS other Nordic networks reach each other through.
• Three company names across the netnames, plus ABB's own /17 carried inside, is a backbone assembled by acquisition. IP-Only survives in the AS handle, DGC in the reverse zone, and GlobalConnect on the deeds.
