FOr part B We are not considered 1st and last bit in time of host calculation 8 because 1st ip is subnet id if few year back we cannot assign that ip , and if all host bits are 1 then it became DBA. hence we need to neglact these, now a days cisco router can use subnet id to assign a host. see if question ask only ip then it will be 2n if ask for host to assign then 2n-2 1 votes 1 votes srestha commented Dec 8, 2017 reply Follow Share thanks:) 0 votes 0 votes Please log in or register to add a comment.
