Summary
IT Right
hosting business
Two customers' bare domains answer on one block, one of them under a top-level domain that did not exist for most of the internet's life.
What it's used for
- A managed IT provider. 512 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The block is
199.21.130.0/23, netnameITRIG-1, registered toIT Right, Inc. - Two of three sampled addresses returned a name:
greenheronpress.comandclarkrd.llc. - Neither name sits under the provider's own domain.
Interesting
- A reverse record pointing at a customer's whole domain rather than a machine under it is what happens when each address belongs to one customer and nobody needed a second. It reads oddly and works fine, and it turns the reverse zone into a client list for anyone who samples the block.
- One of those domains ends in a suffix that names a company structure. Suffixes like that arrived long after the addressing did, so a reverse record can date itself against the block it sits on.
- A single upstream behind a
/23means the AS number here is about holding the addresses rather than about staying up. The provider can move carrier without asking two customers to change anything.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
