Unclassified RIPE
Summary
Net Professionals
business hosting isp
One address answers, and it answers on a domain that has nothing to do with the holder.
What it's used for
- A small provider's network. One IPv4
/24announced from Austria, no IPv6, two hundred and fifty-six addresses, through a single observed BGP neighbour.
Notable
- The netname is the brand contracted to six letters, in lower case, where the registry's convention is capitals.
- The AS handle is the same brand hyphenated in capitals with three letters for an autonomous system, so the two fields disagree about both the spelling and the case.
- The registrants are the company under its legal form and an abuse contact.
- Three addresses were queried for reverse DNS and one answered: a host named after a mail and calendar server, on a two-letter contraction with a number and the country's domain, none of which matches the holder.
Interesting
- A single answering address in a whole block, named after a mail server, is the shape of a small business network where one machine has to be found from outside and the rest does not.
- Naming a host after the software it runs is common and quietly informative. It tells anyone scanning what to expect on the other end before they connect, which is convenient for administrators and equally convenient for everyone else.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,783 prefixes, as published 2026-10-20. 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.
