AS15401 — EOLAS-AS

AS15401 announces 6 IPv4 prefixes covering 8,960 addresses and 1 IPv6 prefixes.

About this network

A customer's brand is readable in one reverse name, alongside the word blog and a number.

What it's used for

• A hosting provider, now part of a large carrier group. Eleven IPv4 prefixes and one IPv6 /32 announced from France, nine thousand addresses, across sixty-two observed BGP neighbours.

Notable

• Five blocks use a netname of country code, company and allocation date; three more carry a hosting brand written as a phrase in the local language; two belong to a different company entirely under its own name.
• One answering address is an edge server numbered five in a zone named after the first letter of a classical alphabet.
• The other names a customer's brand, the word blog and a number, so a site's owner and its role can be read from the address.
• Eighteen addresses were queried for reverse DNS and two returned a name.
• The parent carrier appears in most registrant fields; the operating company's own team appears in all of them.

Interesting

• Sixty-two neighbours for nine thousand addresses is a well connected hosting network. The addresses are the product and the interconnection is what makes them worth buying.
• Naming customer sites in reverse DNS is convenient for the operator and an inventory for everyone else. Anyone can enumerate which brands a hosting provider serves without asking.
• Three separate brands across eleven blocks records a company that was bought and kept selling under its own names, which is normal in this market.
