Summary

Imperva

United States of America · AI-generated

security cdn business

IMPERVA-INC-US-SJ-COLO is operated by Imperva.

What it's used for

  • The address space carries Imperva's web application firewall and CDN infrastructure, evidenced by netnames such as THALES-IMPERVA-NA4-AGG-45-223 and SV2-PUBLIC-SERVICES-SAN-JOSE.
  • The AS announces 2304 IPv4 addresses across 8 prefixes and 3 IPv6 prefixes, with only 2 observed routing neighbours, indicating a dedicated infrastructure network rather than a transit or access provider.
  • Traffic from this AS consists of web security services, including DDoS mitigation and bot management, delivered through Imperva's global edge network.

Notable

  • Registrants include Imperva Ltd., Incapsula Inc, and IMPERVA INC, reflecting the company's history of acquiring Incapsula and subsequent rebranding under the Imperva umbrella.
  • The inventory includes prefixes from multiple ranges, including 185.64.8.0/23 and 198.51.94.0/24, with reverse DNS pointing to ip.incapdns.net, confirming the legacy Incapsula infrastructure.

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 1,783 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.
