解析 Explanation:
If we divide the address 172.25.0.0 in 8 subnets, the resulting subnets will be:
1. 172.25.0.0
2. 172.25.32.0
3. 172.25.64.0
This is the third subnet
4. 172.25.96.0
5. 172.25.128.0
6. 172.25.160.0
7. 172.25.192.0
8. 172.25.224.0
Addresses that fall in the 3rd subnet will be from 172.25.64.0 ---- 172.25.95.255
Choices A, C and D lie in this network range.
