	1.	a.	Report the following decimal numbers as binary and hexadecimal numbers
			Split the binary representation into two 4-bit parts to clarify the binary/hex relationship
			Report hex numbers with a leading 0x to indicate hex
			254				31
			252				63
			248				95
			240				127
			224				159
			192				191
			128				223
							255
			These are subnet numbers used in TCP/IP				These are broadcast addresses
							on a common subnetting scheme
			149
			137
			196
			46
			9
			4
			Some random numbers
		b.	Report these binary numbers as Hexadecimal (preface with 0x) and decimal
			10010110
			101010101
			1011001100110
			10000001
			11110001
		c.	Report the following hexadecimal numbers as binary and decimal
			0xFACE				0x10
			0xFEDBEEF				0x100
			0xFEEDFACE				0x1000
			0xFEEBEEF				0x800
			0x1				0x806
			0xBADBAC				0x8000
	2.	a.	Which RFCs specifically define OSPF
		b.	What does OSPF do?
		c.	Who is the author of OSPF
		c.	What site did you use to find the answers to this question?
	3.	Consider the following network (read ahead or wait for Tuesday's lecture):
			remember there are only three fields to fill in
			The blue lines indicate E'net segments in this exercise and the succeeding one
			Host1 IP: 172.18.5.220			Host2 IP: 172.18.5.10
			Host1			Host2
			MAC: 00-80-C6-F7-37-2D			MAC: 00-80-C6-E3-02.AC
		a.	What will the DIX EthernetII frame header look like if Host1 sends a ping to Host2?
		b.	What will the DIX E'netII frame header for Host2's reply to Host1look like?
		c.	What will the E'net 802.2 frame header look like for an ARP request from Host 1 for Host2's IP address
			(network has been reconfigured to 802.2)?
	4.	Consider the following network (read ahead or wait for Tuesday's lecture)
			The MAC address for each Cisco router interface is next to the IP address for the interface
						IP1: 172.18.5.1
			Host1 IP: 172.18.5.220			MAC: 00-30-19-28-BC-B1			Host2 IP: 172.18.6.10
			Host1			Cisco			Host2
			MAC: 00-80-C6-F7-37-2D			Router			MAC: 00-80-C6-E3-02.AC
						MAC: 00-30-19-28-EF-03
						IP2: 172.18.6.1
		a.	What will the DIX EthernetII frame header look like if Host2 sends a ping to Host1?
		b.	What will the DIX E'netII frame header for Host1's reply to Host2 look like?
		c.	What will the DIX E'netII frame header look like for an ARP request from Host 2 to set up the ping?
	5.	The following MAC address components are in canonical format report them in non-canonical format
		(remember the bits are swapped on a per-byte basis)
		01		This 01 combination in the first byte of an ethernet MAC address indicates multicasting
		C0		(The answer indicates a multicast sort of functional MAC address in Token Ring)
		08
		42
		A5
		3E
