What protocol is used to connect host names to IP addresses?

DNS translates the domain name into IP addresses, and these translations are included within the DNS. Servers can cache DNS data, which is required to access the websites. DNS also includes the DNS protocol, which is within the IP suite and details the specifications DNS uses to translate and communicate.

What is the command to find hostname from IP address?

nslookup
Type “nslookup \%ipaddress\%” in the black box that appears on the screen, substituting \%ipaddress\% with the IP address for which you want to find the hostname.

Which network layer protocol is used if a host without an IP address tries to obtain an IP address from DHCP server?

The DHCP employs a connectionless service model, using the User Datagram Protocol (UDP). It is implemented with two UDP port numbers for its operations which are the same as for the bootstrap protocol (BOOTP).

Which protocol is used to find the IP address the Web server of the host specified in the get message?

The address resolution protocol (ARP) The purpose of ARP is to resolve known IP addresses to unknown physical addresses. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.

Which protocol assign IP address automatically?

DHCP Dynamic Host Configuration Protocol
DHCP. Dynamic Host Configuration Protocol (DHCP) is a protocol that will automatically assign TCP/IP addressing information to workstations over the network (see IETF draft standard RFC 2131, 2132, and 3397). The most common options set by DHCP are the network address, subnet mask, gateway, and DNS server address.

How do I find my host name?

Using the command prompt

  1. From the Start menu, select All Programs or Programs, then Accessories, and then Command Prompt.
  2. In the window that opens, at the prompt, enter hostname . The result on the next line of the command prompt window will display the hostname of the machine without the domain.

How is DNS protocol used?

DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.

What is bootp protocol used for?

BOOTP is a TCP/IP protocol. It allows a client to find its IP address and the name of a load file from a server on the network. A client uses BOOTP to find this information without intervention from the user of the client.

Which network protocol allows hosts to dynamically?

DHCP
Dynamic Host Configuration Protocol (DHCP): It is used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.

What is the difference between IP address and IP protocol address?

An IP address refers to the Internet Protocol address. An Internet Protocol address is your hardware address on the network. E.g., Every computer system has an IP address when it is on a network. An IP address is always unique for all devices connected within a network.

What is dynamic host configuration protocol?

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.

What is the basic purpose of the Address Resolution Protocol?

The basic purpose of the Address Resolution Protocol (ARP) is to resolve IP addresses to ethernet addresses. ARP mediates between broadcast link-level protocols and IP protocols.

How does a DHCP server assign IP addresses?

The DHCP server maintains a pool of IP addresses and leases an address to any DHCP-enabled client when it starts up on the network. Because the IP addresses are dynamic (leased) rather than static (permanently assigned), addresses no longer in use are automatically returned to the pool for reallocation.
