1. List the RFC 1918 private address ranges. 2. True or false: You can use DHCP to specify the TFTP host’s IP address to a client PC. 3. True or false: 255.255.255.248 and /28 are two representations of the same IP mask. 4. True or false: Upper-layer protocols are identified in the IP header’s protocol field. TCP is protocol 6, and UDP is protocol 17. 5. Fill in the blank: Without any options, the IP header is _________ bytes in length. 6. The IP header’s ToS field is redefined as the DS field. How many bits does DSCP use for packet classification, and how many levels of classification are possible? 7. True or false: NAT uses different IP addresses for translations. PAT uses different port numbers to identify translations. 8. True or false: The IP header’s header checksum field performs the checksum of the IP header and data. 9. Calculate the subnet, the address range within the subnet, and the subnet broadcast of the address 172.56.5.245/22. 10.
