What is the number of available hosts contained in the IP address block 222.125.80.128/26, what is the smallest address, and what is the largest address?
IP
/26 is the format of
CIDR
, the full name is classless inter domain route, which is called classless inter domain route, that is to say
, the first 26 bits of the 32-bit
IP are
the network number, and all the latter can be assigned to the host:
parentheses are the host bits, a total of six bits. 2^6=64
Then remove 222.125.80.128, the host address with all zero bits, and 222.125.80.191, the broadcast address , and there are
64-2=62 host addresses left.
The minimum address host bit 00 0001 is 222.125.80.129 The
maximum address host bit 11 1110 is 222.125.80.190
