"To obtain the subnet number, you need to consider only the bits dictated by the subnet mask from the IP address as follow: "
That's exactly my problem. When given only 10.144.33.254/23, I don't know how to read this. So far I know 10.144.33.254 is the IP address, but the slash (/) throws me off... and the 23, I don't remember how to use it
How do you know 1111 1111.1111 1111.1111 1110.0000 0000 (255.255.254.0) is the subnet mask?
The number after the slash signifies the length of the mask. To convert this number to a subnet mask, simply write down that number of 1s, followed by a number of zeros until you have 32 digits in total. For the /23, that gives you:
1111 1111.1111 1111.1111 1110.0000 0000
Note that there are 23 ones followed by 9 zeros.
If you now convert each of the 8-bit blocks into decimal, you get 255.255.254.0
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
