What it's used for
- The address space is registered under the netname
YOUROfor Your.Org, Inc., an organization dedicated to supporting open-source software and contributing to projects like the FreeBSD Foundation. - The network announces a single IPv4 prefix,
199.127.96.0/21, comprising 2048 addresses, with no IPv6 prefixes in inventory. - With only 1 observed neighbour in RIS, the low neighbour count relative to the address block suggests a small, self-contained network rather than a transit provider.
Notable
- The RDAP registrant
YOUR.ORG, INC.matches the AS holder name, confirming consistent ownership. - The address inventory consists of a single contiguous /21 block, indicating a simple, unified allocation without complex subdivision.

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 1,781 prefixes, as published 2026-10-16. 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.
