About this network

Five /24s from five different sources, one of them carrying three generations of carrier ownership.

What it's used for

• An investment management firm's network. 1,280 addresses across five IPv4 prefixes, six observed BGP neighbours, and no IPv6 announced.

Notable

• 62.189.210.0/24 is netname UK-PIPEX-20000720, registered to a company with a maintainer handle naming a second carrier and an abuse contact naming a third.
• 205.138.242.0/24 is netname SAVV-S618717-0, a provider prefix with a service number.
• 167.150.155.0/24 is netname DKCML-2, the firm's initials.
• 8.36.88.0/24 is netname 8-36-88-0-24, the address with dots turned into hyphens.
• One prefix's registry lookup failed, so nothing is known about its registration here.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• That one netname holds a whole ownership history. The provider named in it created the record and stamped it with the date, another carrier bought that provider, and a third bought the second. Each purchase updated the registrant and left the name alone.
• A firm with five /24s and six neighbours has bought a connection in each place it operates and kept the addresses that came with each. The routing table is the only place they look like one network.
