AS13821 announces 13 IPv4 prefixes covering 4,608 addresses and 0 IPv6 prefixes.

About this network

Blocks from three regional registries in one AS, and two of them carry a contact type the third does not have.

What it's used for

• An investment management firm's network. 4,608 addresses across 13 IPv4 prefixes, 13 observed BGP neighbours, and no IPv6 announced.

Notable

• Eleven blocks are netname ALLIANCE-NY, registered to the firm.
• 103.216.134.0/24 is netname ABAL-AU and 165.101.85.0/24 is AJL-JP, each ending in a country code.
• Both of those carry an incident response team object, a field the American records do not use.
• The Australian block's registrant capitalises the company differently from every other record here.
• Its administrator field names a predecessor company rather than the current one.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A firm operating in three registry regions ends up with three record formats for the same organisation. The two overseas objects name a team responsible for handling abuse reports, which is required there and optional elsewhere, so the same company is documented to two different standards.
• A predecessor name surviving in an administrator field, next to the current name in the registrant field, dates that object to before a merger and shows only half of it was updated.
• Thirteen upstreams for four and a half thousand addresses is a firm buying paths rather than space.
