netskope-rdns.comand netnames such asNETSKandNetskope_global_1. - With 187,392 IPv4 addresses across 91 prefixes and 325 observed neighbours, the high neighbour count relative to the address block size indicates a transit-heavy role for a large-scale enterprise network.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
