Subnetting concept and Masking
How many subnets & hosts per subnet are possible if m bits are borrowed from host ID (HID). a) 2^m,2^(HID-m)-2 b)2^m,2^(HID-m) c)2^m-2,2^(HID-m)-2 d)2^m-2,2^(HID-m). The number of subnets will be 2^m but confused with number of hosts per subnet why.

1st seq number is 1093, 2ns seq is 1094, ... 1460th seq number will be 2552. So the ack number sent by the reciever will be 2552+1=2553. Is this right? Answer in solution given is 2554.
