Two addresses answer with a name that says they are unallocated.
What it's used for
- A service provider's network. Three IPv4 prefixes and one IPv6 prefix announced from the United States, seven hundred and sixty-eight addresses, through fifteen observed BGP neighbours.
Notable
- Two blocks are the holder's own. One netname is the two-word name; the other appends three letters and a digit that name no place or function a reader can recover.
- The third block belongs to a different company, under a netname beginning with the word legacy, then a brand, then the word block and a counter.
- Eight of nine queried addresses answered, and they are hand-named machines rather than generated ones: a test host, a numbered mail exchanger, a machine for remote virtualisation.
- Two of them answer with the word unallocated on the holder's own domain.
- Two more answer on domains belonging to other projects entirely, one for blogging and one for a separate piece of software.
Interesting
- A reverse name reading unallocated is an intentional placeholder. The operator filled the zone so every address answers something, and chose to state plainly that nothing lives there yet. Most operators leave the gap silent instead.
- Fifteen upstreams for seven hundred addresses is among the highest ratios in this corpus, and says reachability from many directions matters more here than size does.

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 1,783 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.
