Summary
AppRiver
saas security email business
AS-APPRIVER is held by AppRiver LLC.
What it's used for
- The address space carries SaaS email and web security infrastructure, evidenced by reverse DNS entries such as
spfaus-ryw-q.zixsmbhosted.comandserver70e.appriver.com. - The AS announces 4,864 IPv4 addresses across 7 prefixes and maintains 5 observed neighbours, a ratio consistent with a service provider network rather than a large access or transit backbone.
- Traffic from this AS consists of business email, web security, and SaaS application endpoints for AppRiver's customer base.
Notable
- Registrants are mixed: most prefixes are registered to APPRIVER LLC, while
207.195.184.0/21is registered to Open Text Corporation and64.74.53.0/24to Unitas Global. - AppRiver is now formally part of the OpenText family, which explains the Open Text registrant on the largest prefix.
- The inventory includes a mix of legacy and current AppRiver blocks, with netnames reflecting both
LVLT-(Level 3/Lumen) andCM2-(CenturyLink) histories.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
