Understanding IP Addressing B-181

addresses.

Note any planned and currently used static addresses before you use DHCP and MacIP.

Avoid fragmenting your block of IP addresses. For example, tr y to use a continuous range for the static
addresses you choose.

The figure above shows an example of a block of IP addresses being distributed correctly.

The example follows these rules:

An IP address must not be used as a static address if it is also in a range of addresses being distributed
by DHCP or MacIP.

A single IP address range is used by all the address-ser ved clients. These include DHCP, BootP, MacIP, and
WAN clients, even though BootP and static MacIP clients might not be considered ser ved.

The address range specified for address-ser ved clients cannot wrap around from the end of the total
available range back to the beginning. See below for a fur ther explanation and an example.

The network address issued by an ISP cannot be used as a host address.
