This article describes how to view which IP addresses are currently "in use" or "exclusively reserved" on a VLAN in an MCP 2.0 Data Center location. This is relevant when deleting a VLAN since all IPv4 and IPv6 Addresses must be unreserved and not in use before you can delete it.
Addresses returned by this function may be listed for a number of reasons, including:
- IP address is being used by a NIC on a Cloud Server
- IP address is being used as the "internal IP" of a NAT
- IP address is being used as a Node
- IP address has been exclusively reserved as described in How to Exclusively Reserve an IPv4 or IPv6 Address. This prevents use by any of the functions above.
