7 3 points An ISP has CIDR block 135.102.192.0/22. The ISP wants to create 4 sub-blocks of equal size from this block. a. How many bits should the ISP add to the mask for the subblocks? b. What are the network addresses (in dotted decimal with the mask in slash notation) for each subblock? c. What is the maximum number of actual hosts in each subblock? Drag n' Drop here or Browse 8 8 points Your boss wants you to design subnets to support a new office. The office has three floors and each floor should be a subnet. The net id for the entire site is 100.10.172.0/24 The LAN on the first floor must be able to support at least 50 hosts. The LAN on the second floor must be able to support at least 25 hosts. The LAN on the third floor must be able to support at least 10 hosts. o You must have one unused subnet for future expansion 9 & 2 points Answer the following questions concerning the IPv4 and IPv6 protocols: An IPv6 datagram consists of the following in the stated order): Base Header, Fragmentation Header, TCP Segment. What will be the Next Header field in the Base Header? Fragmentation Header O Authentication Header Routing Header & 10 2 points Answer the following questions concerning the IPv4 and IPv6 protocols: IPv4 headers have a protocol field that indicates what protocol was used to create the payload. Why is there no protocol field in the IPv6 base header? If there are no extension headers, the next header field contains a code indicating the protocol used to create the payload. IPv6 packets do not have payloads O The receiver figures out what kind of payload it is by examining the payload O The only possible payload for IPv6 is TCP 13 2 points An IPv6 packet contains the base header, two 20 byte extension headers, and 1200 bytes of payload data. a. What value is in the payload length field? type your answer... b. How many total bytes are in the packet? type your answer... {Hint: the size of the base header is fixed. You need to look it up.} Submit 11 2 points Answer the following questions concerning the IPv4 and IPv6 protocols: What is the purpose of the Hop Limit field in the IPv6 header? O It indicates the quality of service requirements Olt indicates the number of bytes in the header Olt indicates whether the packet is a fragment or not O lt detects lost packets 12 2 points -10 An IPv4 packet has 800 bytes of payload data and a 32 byte header. a. What values will be in the HLEN (also called IHL) field in the header? type your answer... b. What value will be in the Total Length field in the header? type your answer... 13 2 points An IPv6 packet contains the base header, two 20 byte extension headers and 1200 butes of
