Suppose the ranges of the IP addresses that are available for your IP Telephone network
are:
135.254.76.7 to 135.254.76.80
135.254.76.90 to 135.254.76.200
135.254.76.225 to 135.254.76.230
Your start address and end address should then be 135.254.76.7 and 135.254.76.230,
respectively.
You should exclude the ranges 135.254.76.81 to 135.254.76.89 and 135.254.76.201 to
135.254.76.224.
