AS14636 — INTERNAP-BLK4

AS14636 announces 11 IPv4 prefixes covering 11,264 addresses and 1 IPv6 prefixes.

About this network

Its IPv6 announcements form a doubling ladder, each prefix twice the size of the one before, all the way from /46 to /38.

What it's used for

• A hosting and network services provider. 11,264 addresses across 14 IPv4 prefixes plus 15 IPv6 prefixes, with two observed BGP neighbours.

Notable

• The sampled IPv6 prefixes climb in a chain under 2404:1200: two /46s, then a /45, /44, /43, /42, /41, /40, /39 and /38.
• Blocks carry HIQPLATFORM-V4-5 and HIQPLATFORM-V4-8, registered to Internap Holding LLC.
• 72.5.160.0/23 carries the netname PNAP-09-2004, a date in the label.
• Four blocks carry INTERNAP-SG-AGILE1, INTERNAP-SG-AGILE2 and PNAPSG-SG-001, registered through a Singapore entity with a HorizonIQ Network Engineering contact.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A doubling ladder is what a router produces when it splits a large allocation into the smallest number of pieces that can cover a range with a hole in it. Each step doubles because binary addressing leaves no other option, and the result reads like a staircase.
• Three brand names appear across the records: the AS name, an abbreviated platform prefix on the netnames, and a network engineering contact under a fourth name. Each rebrand added a layer without removing the one below.
• Announcing IPv4 from four continents' worth of ranges under one AS is what a provider does when it sells the same service in many facilities.
