About this network

A netname with the date of the assignment baked into it.

What it's used for

• An investment firm's network. 1,536 addresses across five IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• 45.128.84.0/23 carries the netname UK-STEPHENSEUROPE-20190711, registered to a European subsidiary with an abuse role as contact.
• The other four blocks carry STEPHE-1 and name a support services network team.
• Those four are 204.110.192.0/24, 204.110.195.0/24, 204.110.197.0/24 and 204.110.198.0/24, leaving three gaps in the run.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• The eight digits at the end of the European netname are the date the block was assigned. That convention is standard in one registry and absent in the other, which is why the same company's records read so differently depending on which region issued them. It also means anyone can date the European arm's arrival on the internet from a registry field alone.
• The gaps between the four older blocks are the fingerprint of address space handed out one piece at a time over years, with other organisations taking the pieces in between. Four announcements where one would do is the cost.
• A financial firm publishing nothing in reverse DNS and running only two upstreams is behaving exactly as it should: the network exists to reach a small number of counterparties and market services, not to be found.
