About this network

One hostname escaped the reverse zone, and it names a service, a business line and a recovery site in three labels.

What it's used for

• An investment bank's network. 9,472 addresses across 12 IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Most blocks carry the netname BARCLAYS-CAPITAL, registered to Barclays Capital.
• Three blocks in 167.203 carry BARCLAYS-AMER and BARCLAYS-NA with no registrant recorded.
• One of eighteen sampled addresses returned a name: ftpdr.prime.barcap.com.
• The AS handle is the full AS name rather than a short code.

Interesting

• That one hostname is more revealing than the other seventeen silences. The labels name a file transfer service, a suffix used for disaster recovery, and a business line, all under an abbreviated corporate domain. Anybody watching for a bank's failover systems now knows what to look for.
• Netnames ending in regional abbreviations, with the organisation field empty, are records inherited rather than created. The label survived a reorganisation that the registrant field did not.
• Twelve announcements at sizes from /21 to /24, spread over four unrelated ranges, is an estate gathered across decades of mergers. Investment banks change names more often than they change addresses.
• Two neighbours for a bank of this size means the visible internet edge is small. The trading traffic that matters travels over private circuits that never appear in a routing table at all.
