Question 29 0/1 pts What is the net id and the host id for the IP address 223.128.128.128 with the subnet mask 11110000 00000000 0000000000000000 netid = 0.128.128.128 and hostid = 223.0.0.0 You Answered netid = 223.0.0.0 and hostid = x. 128.128.128 This implies 255.0.0.0 is the subnet mask. netid=223.128.0.0 and hostid = x.x.128.128 Correct Answer netid = 208.0.0.0 and hostid = 15.128.128.128 Question 30 1/1 pts We wish to create 30 subnets in a /16 network.(Assume that we wish to use the minimum number of bits for the subnet id.) How many bits are used for the subnet id? Correct! 5bits 4bits 6bits 30bits
