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.
