Summary

hosting isp business
The AS handle is not a label. It is a country, a comma, and a list of the three services on offer.
What it's used for
- A hosting provider's network. Fifty-three prefixes announced from Spain, one of them IPv6, eighty-nine thousand three hundred and forty-four addresses, through ten observed BGP neighbours.
Notable
- The AS handle joins the brand to the letters for an autonomous system with an underscore, then adds a country and three services separated by commas. It reads as advertising copy.
- Most blocks use a country code, the brand, and a full date, with dates spread over seven years.
- Two use the brand alone. One is named after a national carrier instead, and is registered to that carrier's administrators and technical staff.
- The abuse contact splits by family. The dated blocks name the company itself; the undated ones and the carrier's block name a fourth brand's abuse team.
- The same three contacts appear on most blocks in two different orders, so the listing order is not meaningful.
- Five of eighteen queried addresses answered. Three carry the address hyphenated, a word for networks, and the provider's domain. Two are customer machines on unrelated domains, one of which begins with a number.
Interesting
- Selling hosting means somebody else's hostnames live on your addresses. Two answers in this sample name a mail server and a directory server on domains the registry has never heard of.
- A registry handle used as a sales pitch dates from when these fields were read by humans. Nothing validates it, so it survives.

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.
