ip addressing 255 usage

[j.lipsett]

IP range 25.76.64.0 255.255.252.0 will give you the following range - 64.1 to 67.255.

can you use 64.255. 65.255. 66. 255 as user addresses? 67.255 is the broadcast address.

Yes, I believe you can. You cannot use all ones norall zeros in an address within a subnet, making the first and last address within a subnet unuseable. Since 64.255 has two zeros, 65.255, and 66.255 have one zero each, this satisfies the condition.

25.76.64.0/22 is the network address, and 25.76.67.255/22 is the broadcast address.

Definitely.

Your usable IP addresses are determined by the netmask. If a subnet is larger than a /24, you will have ".255" addresses that are usable in that subnet. You can use them without any problems.

That's great.
