Summary

hosting business infrastructure
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
/29announced 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.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
