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, try 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-served clients. These include DHCP, BootP, MacIP, and
WAN clients, even though BootP and static MacIP clients might not be considered served.
■ The address range specified for address-served clients cannot wrap around from the end of the total
available range back to the beginning. See below for a further explanation and an example.
■ The network address issued by an ISP cannot be used as a host address.
