Unformatted text preview: This file contains the number of domestic and foreign networks announced to the NSFNET infrastructure. Plot these values with the year on the x-axis and a logarithmic y-axis with the total number of networks. The maximum value for the y-axis should be the value calculated in the previous exercise. If the data shows a visual trend, extrapolate the values to estimate when the current addressing scheme will run out of network IDs. (Section 3.10 talks about proposals to correct this problem.) 1.3 Obtain a copy of the Host Requirements RFC [Braden 1989a] and look up the robustness principle that applies to every layer of the TCP/IP protocol suite. What is the reference for this principle? 1.4 Obtain a copy of the latest Assigned Numbers RFC. What is the well-known port for the "quote of the day" protocol? Which RFC defines the protocol? 1.5 If you have an account on a host that is connected to a TCP/IP internet, what is its primary IP address? Is the host connected to the worldwide Internet? Is it multihomed? 1.6 Obtain a copy of RFC 1000 to learn where the term RFC originated. 1.7 Contact the Internet Society, [email protected] or +1 703 648 9888, to find out about joining. file:///D|/Documents%20and%20Settings/bigini/Docu...homenet2run/tcpip/tcp-ip-illustrated/introduc.htm (19 of 20) [12/09/2001 14.46.31] Chapter 1.

TCP/IP supports many different link layers, depending o...
