Summary

Netskope

United States of America · AI-generated

security cloud business infrastructure

NETSKOPE is operated by Netskope Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to netskope-rdns.com and netnames such as NETSK and Netskope_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.
  • As a cybersecurity company providing cloud security and network transformation solutions, this AS hosts the company's global platform endpoints, data centers, and internal network operations.

Notable

  • Registrants largely align with the announcer, with Netskope Inc listed for most major prefixes, though one block (146.92.0.0/20) is registered to BMO Harris Bank National Association.
  • The company was formerly known as Skope, Inc. and changed its name to Netskope, Inc. in November 2012.
  • The inventory consists of multiple large /17 and /19 blocks alongside numerous smaller /20 and /21 subdivisions, reflecting a finely segmented internal corporate estate.

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 1,771 prefixes, as published 2026-10-15. 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.
