IP intervals
Thisis a list of the IP addresses available for different netmasks. The first column shows the number of bits used for
thenet address, i. e., is set to 1 in the netmask. The second column maps the number of bits to a netmask on the
usualoctet-dot format. The third column shows the address class for this netmask.
Thesecond table shows the IP address interval for each class.
