Subnetting

Hi Team,

What valid host range is the IP address 10.255.207.175/20 a part of?

Answer: 10.255.192.1 through to 10.255.207.254

i know the concept but is there any simple and quick solution to find the first valid host address, because the IP in question is 10.255.20.175, how to guess the IP will be starting from 10.255.192.0 for this range.

Hope you got what am trying to ask.

Thank You,

what about subnet's because when i calculate it with subnet calculator it is showing

for 10.100.25.2 with subnet mask 255.255.255.192

total host = 64 and total subnet = 262144

for 192.168.25.2 with subnet mask 255.255.255.192

total host = 64 and total subnet = 4

how is it ?
