2 votes 2 votes For subnetting you should buy bit from network id only. junaid ahmad answered Jun 16, 2017 junaid ahmad comment Share Follow See 1 comment See all 1 1 comment reply AnilGoudar commented Jun 16, 2017 reply Follow Share For class A ip address, we have 8 bits for Netwoork ID, but while creating SUBNET, we will keep these 8 bits as it is and then choose one of the bit from the host Id to create two subnets within the same network. using the decimal octet representation, let Ip address be 10.0.0.0, we can create two subnet as, 10.0.0.0 and 10.128.0.0 created as, 10. 0 0 0 0 0 0 0 0 . 0. 0 and 10. 1 0 0 0 0 0 0 0 . 0 . 0. In this we have used host part of the ip address. Please correct me if i am wrong. 0 votes 0 votes Please log in or register to add a comment.
1 votes 1 votes In subnetting, We know that SubnetID bits + NetID bits= Mask bits eg:let we have subnet mask of 27 bits and we have given address of CLASS C i.e. 24bits . Also we know that Host ID bit will be of 8bit. 24+S=27 Then S=3 Now to make a subnet having 3bit we need to take 3bit from host ID bits... We can see that NetID bits remains unaffected while host Id bits reduced Hope u understands RiteshSingh answered Jun 16, 2017 RiteshSingh comment Share Follow See all 2 Comments See all 2 2 Comments reply AnilGoudar commented Jun 17, 2017 reply Follow Share Is the answer written by Junaid is correct?

1 votes 1 votes In subnetting, we borrow bits from the host id or part. And, In supernetting, we borrow bits from network id or part. I think, we are combining one or more networks together in supernetting. nailwalhimanshu answered Jun 20, 2017 nailwalhimanshu comment Share Follow See all 0 reply Please log in or register to add a comment.
