Network Address Translation (NAT) in TCP/IP
Network Address Translation (NAT) is used by organizations where they can use the TCP/IP protocol for internal and global communication. They use private block addresses for internal communication but, for communication with the world, organization needs at least one global internet address.
A technology that can provide the mapping between private and global addresses is known as Network Address Translation (NAT). So in this video, we will see how, many computers of one organization can communicate with the internet via a single global address via Network Address Translation.

The DHCP (Dynamic Host Configuration Protocol) is a client/server protocol designed to provide the four pieces of information for a diskless computer or computer that is booted for the first time. These four pieces are 1. The IP address of the computer 2. The subnet mask of the computer 3. The IP address of a router 4. The IP address of a name server Normally, a DHCP server has a database with ...

Internet Control Message Protocol (ICMP) works as companion protocol of IP which used to convey the errors and information to original host. ICMP messages are of two types first is error-reporting messages and second is query messages. The error-reporting messages report problems that a router or a host may encounter when it processes an IP packet. The query messages help a host or a network ma...

ARP - Address Resolution Protocol Fully Explained
Переглядів 6522 роки тому
ARP (Address Resolution Protocol) is used to map Internet Addresses to Physical Addresses. The IP protocol delivers a packet from a source host to the destination host, so it needs to know how to deliver it to the next hop first. An IP packet can consult its routing table, to find the IP address of the next hop. But since IP uses the services of the data link layer, it needs to know the physica...

Переглядів 9 тис.2 роки тому
There is a chance of data corruption and error during the transmission of packets. The checksum is used to check such errors in most of the TCP IP protocols. The checksum is calculated at the sender and the value obtained is sent with the packet. The receiver repeats the same calculation on the packet including the checksum. If the result is satisfactory, the packet is accepted; otherwise, it i...

Переглядів 1,8 тис.3 роки тому
In classless addressing in IPv4, we need to include the prefix length to each address if we need to find the block of the address. In this case, the prefix length, n, is added to the address separated by a slash. The notation is referred to as slash notation. The slash notation is formally referred to as Classless Inter Domain Routing or CIDR notation. This video explains not only CIDR but also...

In classful addressing it was assumed that the whole Internet is divided into many networks and each network contains many hosts. Since all addresses in a network belong to a single block, each address in classful IPv4 addressing contains two parts like netid and hostid. The netid defines the network, and the hostid defines a particular host connected to such network. Router decides which packe...
