Summary

Vertafore

United States of America · AI-generated

business insurance corporate

AS26584 is operated by Vertafore, Inc.

What it's used for

  • The address space is carried by a mix of legacy netnames, including AMSSE for the largest block and CENTURYLINK-LEGACY-SAVVIS for smaller /23s, indicating a corporate estate assembled through acquisitions.
  • With 2560 IPv4 addresses across 4 prefixes and only 3 observed neighbours, the low neighbour count relative to the address inventory suggests an internal corporate network rather than a transit or access provider.

Notable

  • Registrants do not fully align with the announcer; while VERTAFORE, INC holds the primary /22, Level 3 Parent, LLC and CenturyLink Communications, LLC are listed as registrants for the remaining prefixes, reflecting historical ownership changes.
  • Vertafore is a technology company serving the insurance industry, and the AS number has been active since 2003.
  • The inventory consists of four distinct IPv4 prefixes with no announced IPv6 space, showing a fragmented but small-scale address footprint.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
