AS14821 — VLAN24-INC

AS14821 announces 6 IPv4 prefixes covering 6,144 addresses and 3 IPv6 prefixes.

About this network

Ten prefixes assembled from four registries, two of them still registered to the carriers they came from.

What it's used for

• A hosting and connectivity provider's network. 6,144 addresses across 10 IPv4 prefixes and three IPv6 prefixes, with six observed BGP neighbours.

Notable

• Six blocks in 45.58 carry the netname VLAN24; 208.72.36.0/24 carries VLAN24-B and 69.174.107.0/24 carries VLAN24-INC-GTT, named after the carrier it came from.
• 103.89.68.0/22 carries VLAN24-AP with an incident-response team entry, filed in a different registry.
• 8.3.242.0/24 is registered to Level 3 Parent, LLC and 153.254.111.0/24 to Japan Network Information Center.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Five different naming conventions for one company's space is what growth by opportunity looks like. Each block came from whoever had addresses free at the time, and the label records the source rather than the use.
• A /24 from the 8.3 range is a fragment of one of the earliest allocations ever made, now leased in pieces. So is the Japanese block, held by that country's registry and announced from a network filed as American.
• Address space with this many origins is worth more than the routing suggests. It is why a small provider bothers to announce ten prefixes instead of consolidating.
