AS12665 — MSH Autonomous System

AS12665 announces 5 IPv4 prefixes covering 15,872 addresses and 2 IPv6 prefixes.

About this network

A block whose contact and registrant differ by a letter transposition: MSH against MHS.

What it's used for

• Media and systems hosting in Germany. 15,872 addresses in five IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 195.238.128.0/19 is netname DE-MSH-970102, dated the second day of January 1997.
• Three blocks share DE-MSH-990923: 212.4.224.0/20, 212.4.244.0/22 and 212.4.248.0/21.
• 195.191.42.0/23 is netname SIR-NET, registered to MHS Digital GmbH with MSH Hostmaster as its contact.
• Fifteen sampled addresses were queried and none returned a name.

Interesting

• MSH and MHS on the same record, one as the contact and one as the registrant, differ only in the order of two letters. Whether that is a rebrand, a related company or a typing slip is not something the registry can answer, and either way both spellings are now official. Three letters in a different order is exactly the kind of difference that automated matching gets wrong in both directions.
• The January 1997 date is among the oldest here, and the second of January is a working day chosen by whoever came back from the holidays with a form to file.
• Three separate announcements out of 212.4.0.0 sharing one netname and one date is the same pattern that shows up repeatedly in this range: the split happened after the allocation, for internal reasons, and every router on the Internet carries the result.
