AS16055 AADD-
Unclassified RIPE
Summary
AADD
isp hosting business
The AS handle is four letters and a trailing hyphen, cut off before whatever came next.
What it's used for
- A provider's network. Three IPv4 prefixes announced from Austria, no IPv6, one thousand seven hundred and ninety-two addresses, through a single observed BGP neighbour.
Notable
- The handle ends in a hyphen with nothing after it, so the field was truncated at the exact point where a country code or a suffix would have followed.
- The three netnames use three conventions: the country code with the brand and a date, the brand with the word for a network, and a five-letter label in lower case that matches nothing else in the record.
- That third block is registered to a private individual, with the company appearing only as the hostmaster contact beneath.
- Every block carries the same hostmaster role, written as the word for hostmaster followed by the full company name including its legal form.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- An individual holding a block that a company announces is one of the oldest arrangements in the registry. Address space was assigned to whoever asked, and small networks were often requested by one person who then built a business around them.
- A trailing hyphen is a good marker of a copied field. Somebody pasted a prefix meaning to complete it, and the record has been served that way ever since.

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 2026-10-17. 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.
