3.1    Must the loopback address be 1 27.0.0.1? IP is the core protocol in the TCP / IP protocol family. All TCP , UDP ,ccna 200-301 wendell odom pdf, ICMP and IGMP data are transmitted in IP datagram format (see Figures 1-4 ). Many people who are new to TCP / IP are surprised by the fact that IP provides unreliable, connectionless datagram delivery services, especially those with X.25 or SNA background. 4.5.2    ARP Request for Non-Existing Host 3.3 IP routing The RARP request is broadcast ( line 1 ), and the RARP response in line 2 is unicast. The output of line 2 atsun indicates that the RARP response contains the IP address of the host sun ( 1 40. 2 5 2. 1 3. 3 3 ). Here, we list an FTP client program and another FTP server program. Most web applications are designed as client-server models. The server provides a certain service to the client, in this case accessing files on the host where the server is located. In the remote login application Te lnet , the service provided to the client is to log on to the server host. At 7. 3 section, we describe the IP record route option ( RR ). Why not use this option to develop a new application? There are three reasons. First of all, originally not all routers support the record routing option, so this option cannot be used on some paths (the Traceroute program does not require the intermediate router to have any special or optional features). • next (or next-hop) router ( Next-Hop Router ) of the IP address, the network has a direct connection or IP address. The next router is a router on a directly connected network through which datagrams can be forwarded. The next router is not the final destination, but it can forward the datagrams sent to it to the final destination. Most products support the Loopback Interface to allow client programs and server programs running on the same host to communicate via TCP / IP . The class A network number 1 2 7 is reserved for the loopback interface. By convention, most systems the IP address 127. 0. 0.1 is assigned to this interface, named localhost . An IP datagram passed to the loopback interface cannot appear on any network.
