For more details, please refer to the Difference between Ping and Traceroute article.Ĭontrol connection: For sending control information like user identification, password, commands to change the remote directory, commands to retrieve and store files, etc., FTP makes use of connections. It also shows the time is taken (or delays) between intermediate routers. It shows you the complete route to a destination address. Traceroute is a widely used command-line utility available in almost all operating systems. For more details, please refer to the Difference between Ping and Traceroute article. ICMP (Internet Control Message Protocol) is used by PING. This is used to discard the packets that are stuck in an infinite loop because of some routing error.įor more details, please refer to Internet Protocol version 6 (IPv6) Header article. Its value gets decremented by one, by each node that forwards the packet and the packet is discarded if the value decreases to 0. It indicates the maximum number of intermediate nodes IPv6 packet is allowed to travel. Hop Limit: Hop Limit field is the same as TTL in IPv4 packets. The gateway is also associated with both a router, which uses headers and forwarding tables to determine where packets are sent and a switch, which provides the actual path for the packet in and out of the gateway.įor more details, please refer to Working of different layers in the Computer network article. In such a situation, the gateway node could also act as a proxy server and a firewall. The default gateway commonly connects the internal networks and the outside network (Internet). In organizational systems, a gateway is a node that routes the traffic from a workstation to another network segment. For more details, please refer Local Broadcast and Loopback address article. Loopback Address is used to let a system send a message to itself to make sure that the TCP/IP stack is installed correctly on the machine. For more details, please refer CIDR full-form to the article. Since there are these problems, Classful networking was replaced by Classless Inter-Domain Routing (CIDR). Class D addresses are used for multicast routing and are therefore available as a single block only.
The problem with this classful addressing method is that millions of class A addresses are wasted, many of the class B addresses are wasted, whereas, number of addresses available in class C is so small that it cannot cater to the needs of organizations. So, in order to get the network to which the destination address belongs, we have to bitwise & with a subnet mask. 1’s represents network and subnet ID while 0’s represents the host ID. The subnet mask is a combination of 1’s and 0’s.
