The Manage > External Networks page displays the following information for external networks that are currently in your system:
NETWORK NAME: The external network name.
DESCRIPTION: An optional description for the external network.
SUBNET: The logical subdivision of an IP address. Both IPv4 and IPv6 IP addresses are supporting when configuring subnets. To avoid duplicate networks and issues with ACLs defined for the DNS Firewall, BloxOne Threat Defense does not allow a CIDR block that spans a wide range of IPs. You can enter a valid netmask between /24 and /32. BloxOne Threat Defense will return an error if you enter an invalid netmask. IPv4 subnets larger than /30 and IPv6 subnets larger than /56 will be verified by the Infoblox support team prior to becoming operational.Please allow 5 business days for support team verification. For addition information about Subnets, see External Subnets.
