How To Make Zenoss Prefer IPv4 Addresses When IPv6 is Enabled

Applies to

    Zenoss 4.1.1, 4.2.3, 4.2.4

Summary

Because the system wide default on modern Linux operating systems has moved towards presenting IPv6 addresses first, the IPv6 address is often what Zenoss ends up with when a device is added by FQDN. If you prefer to favor IPv4 addresses for your devices within Zenoss you have two basic options:

  • Disable IPv6 on the kernel (if running in an IPv4 environment only)
  • In a dual stack environment prepare separate hostnames for IPv4 (A record) or IPv6 (AAAA record) and monitor your device by the appropriate hostname.
