AS13737 — AS-INCX

AS13737 announces 40 IPv4 prefixes covering 13,568 addresses and 23 IPv6 prefixes.

About this network

One IPv6 block is announced in eight pieces that each double the last, and another the same size as a single route.

What it's used for

• A wholesale internet and hosting provider. 12,288 addresses across 35 IPv4 prefixes, 33 IPv6 prefixes, and 23 observed BGP neighbours.

Notable

• 2602:f895::/47 through 2602:f895:80::/41 are eight announcements that each double the previous one and together tile a single /40 exactly.
• 2602:f8c7::/40 covers the same amount of space in one route.
• Six different companies appear as registrants across twelve sampled blocks.
• 104.244.208.0/22 is netname AS13737-IPV4-BLK-1, naming this AS number.
• 23.172.168.0/24 is netname AS975-IPV4-1, naming a different AS number entirely.
• 45.141.13.0/24 is netname SMARTHOST-LEASE, registered to a role object rather than a company.
• Some addresses answer under another provider's DSL zone, as dsl253-125-000.lax1.dsl.speakeasy.net.

Interesting

• Doubling pieces covering one block exactly is the shape a network takes when it grows into an allocation a step at a time and never withdraws the earlier routes. The parent could be announced as one line and instead occupies eight, while the block next to it does the opposite.
• A netname carrying a different AS number inside this AS's announcements records who the space was numbered for before it moved here. The registry kept the old owner's label.
• The DSL names carry a site code and a zero-padded octet, a naming scheme from a network that no longer runs the addresses.
