AS15692 — RAZORBLUE

AS15692 announces 9 IPv4 prefixes covering 4,096 addresses and 1 IPv6 prefixes.

About this network

Forty-two neighbours for four thousand addresses, and every one of them answers to the same template.

What it's used for

• A managed services and hosting provider. Nine IPv4 prefixes and one IPv6 prefix announced from the United Kingdom, four thousand and ninety-six addresses, across forty-two observed BGP neighbours.

Notable

• Seventeen of eighteen sampled addresses answer, and every name is the four octets hyphenated, followed by the word for a fixed address, followed by the company domain.
• That includes the network and broadcast addresses of each block, which get the same name as any other address.
• All nine blocks share one netname convention with seven different allocation dates, spread across more than a decade.
• Every block lists the company's own abuse handler rather than the registry's generic role.
• The IPv6 announcement is a /30, larger than the standard opening allocation.
• Nine separate blocks from eight unrelated ranges make up four thousand addresses.

Interesting

• Forty-two neighbours is ten times what a network this size usually carries. The address count measures what a provider holds; the neighbour count measures how many places it chose to connect, and those are independent decisions.
• Generating names for every address in a block, structural ones included, is the cheapest correct answer. It costs one template, it never goes stale, and it tells a reader nothing beyond the address they already had.
