CORRECT TEXT
An ISP has given an administrator an IP block for use. The block is 192.168.112.64/26. If the
administrator uses the first usable IP for the router that is installed on the network, how many
usable IPs are left? (Please enter the number and not a word)
Answer: 61
62 ??
61 is right.
/26 —> 64 – 2 = 62 free ips
If the administrator uses the first usable IP for the router that is installed on the network = 62 -1 = 61
