AS14999 — USERWORLD

AS14999 announces 1 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

The last number in this range, and the smallest network in it.

What it's used for

• A small provider's network. 512 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

• The whole footprint is 199.27.148.0/23, half the size of almost every other network in this range.
• The netname is USERWORLD, matching the AS handle and the registrant exactly.
• The registrant differs from the AS name only in where the full stop falls after the company suffix.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• 512 addresses with one upstream is the minimum arrangement that justifies holding an AS number at all. Below this there is no reason not to take addresses from a provider and skip the paperwork entirely, which is what nearly everyone does.
• Every field agreeing is the mark of a record filed once, by the person who runs the network, and never handed to a carrier's provisioning system to be rewritten. Most of the inconsistencies catalogued across this range come from that handover.
• The company name reads as a product from the era when getting people online was itself the product. It has been announcing continuously since the routing archives begin, which makes it one of the longest-lived small networks here.
• No IPv6 and a single carrier is a network that works and has not been asked to do anything else.
