Excluding IP Addresses That Are Not Automatically Allocated

Excluding IP Addresses That Are Not Automatically Allocated

During network planning, some IP addresses in an address pool may be used by servers or other hosts, or some clients can be configured with specified IP addresses only because of special requirements. In this case, you need to exclude these IP addresses that cannot be automatically allocated from the address pool, preventing IP address conflicts.

Exclude IP addresses that cannot be automatically allocated from the address pool on a switch as a DHCP server. For example, exclude IP addresses 10.1.1.100 to 10.1.1.200 from the address pool with the network segment address 10.1.1.0 and mask length 24.
