business saas insurance internal

ZYWAV-MKE-ASN is held by Zywave Inc.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames ZYWAVE and ZYWAV-1 assigned to registrant Zywave.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 4 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of web and API endpoints for Zywave's SaaS insurance platforms, serving office workers and client-facing applications.

Notable

  • Registrants Zywave and ZYWAVE INC align with the announcer, confirming the space is owned by the operator.
  • Zywave acquired Intygral in July 2015, absorbing its insurance technology assets into its own platform.
  • The inventory consists of two /24 blocks, 162.250.10.0/24 and 209.188.107.0/24, with no IPv6 prefixes announced.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
