Network type: hosting

AS15456 announces 8 IPv4 prefixes covering 24,576 addresses and 1 IPv6 prefixes.

About this network

One address answers with a domain that says no email address was set.

What it's used for

• A domain registrar and hosting company. Ten IPv4 prefixes and one IPv6 /29 announced from Germany, twenty-four thousand addresses, through two observed BGP neighbours.

Notable

• Eight of the ten blocks carry the same allocation date, so most of this address space arrived in one grant.
• Four answering addresses use the octets fully reversed under a subdomain for reverse and a generic domain about customer networks, not the company's own name.
• The fifth answers with a placeholder domain whose name states outright that no email address was configured.
• Registrant fields list a network crew, the company, and an abuse contact, three entries on most blocks.
• Eighteen addresses were queried for reverse DNS and five returned a name.

Interesting

• That placeholder is a default value escaping into production. Somewhere a form was left blank, a system filled in its stock answer, and it became a public record.
• Naming customer addresses under a neutral domain rather than the company's own is a considered choice. It keeps the hosting brand out of spam reports about individual customers.
• Two upstreams for twenty-four thousand addresses of hosting is thin. The neighbour count is the first thing to question in a record like this.
