AS14717 — ECINET

AS14717 announces 35 IPv4 prefixes covering 23,040 addresses and 2 IPv6 prefixes.

About this network

Two netnames carry the date the block was assigned, ten years apart, and the older half of the estate still wears a defunct backbone's prefix.

What it's used for

• A managed IT provider for investment firms. 23,040 addresses across 38 IPv4 prefixes plus two IPv6 prefixes, 2607:fd90::/32 and 2a02:2ba8::/32, with 24 observed BGP neighbours.

Notable

• Many blocks carry netnames beginning UU- followed by the address and sometimes a code: UU-63-117-56-D4, UU-63-117-160-D1, UU-63-71-180-E1, UU-63-94-92.
• Two are registered to NTT America, Inc. under NTTA-204-141 and NTTA-206-166-128, with a contact recorded as VIPAR.
• Two more sit under Eze Castle Integration - United Kingdom, LTD. with netnames UK-EZEUK-20080904 and UK-EZEUK-20181109, alongside an ECI NOC and an Abuse-C Role.
• Twelve of eighteen sampled addresses returned a name, all writing the address backwards, such as 255.59.117.63.ezecastlehosting.com.

Interesting

• Putting the assignment date in the netname makes the registry self-dating. The two UK records are a decade apart and the format did not change in between, which is rarer than it sounds.
• The UU- prefix belongs to a backbone that has been absorbed twice over. Netnames are almost never rewritten after a transfer, so the prefix outlives the company that issued it.
• A separately incorporated UK entity, its own IPv6 prefix and its own abuse role is a firm that followed its clients to a second financial centre and had to register there as a local.
• Twenty-four neighbours for 38 prefixes is the shape of a provider whose customers care more about latency and reachability than about bandwidth.
