Hosting RIPE
Summary
LEONET
isp hosting telecom business
The AS handle ends in a hyphen with nothing after it, and half the reverse names have no domain.
What it's used for
- A regional provider. Five IPv4 prefixes and one IPv6 prefix announced from Italy, nineteen thousand addresses, across thirty-eight observed BGP neighbours.
Notable
- The handle stops mid-word, leaving a trailing hyphen where the country code should be. The holder string has the code; the handle lost it.
- Three of the six answering names are bare labels with no domain attached at all: a hyphenated pair of words, a business system with a version and a slot number, and a single mythological name.
- A fourth writes the address as ten digits run together with no separators of any kind.
- The other two follow a scheme of their own, naming the last octet and the third octet as separate words before the domain.
- Two netnames carry six-digit dates with two-digit years and a third carries a full eight-digit one, so the changeover is visible inside one holder's records.
- One block belongs to a different company under a different brand. Another block's registry lookup failed, so its details are unknown rather than absent.
- Fifteen addresses were queried and six returned a name.
Interesting
- A reverse record pointing at a name with no domain is valid and close to useless. Anything that looks it up gets a string that resolves nowhere, which is how internal host names escape.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
