RESTRICTED IP RANGES

When setting up dynamic routing, it is important to be aware of the restricted IP ranges that are not available for use. There are two IP address blocks that are restricted:

172.31.0.0 / 16

  • This block is reserved for Virtual Router Loopback IP addresses.

169.254.0.0 / 16

  • This block is reserved for use of link-local IPv4 address space for BGP peering between virtual routers and the cloud provider infrastructure(s).

All other IP ranges are supported by CoreSite and are available for customer use.
