What Is DNS And DHCP?

DNS, Domain Name System Server is used to translate domain names to IP Addresses or used to translate IP Addresses to domain names.

DHCP, Dynamic Host Configuration Protocol Server is used to configure hosts mechanically.

DHCP Server works on ports 67 and 68.

What is the difference between DNS and DHCP?

Difference Between DNS and DHCP. DNS and DHCP both work on the client-server architecture but are dissimilar terms. DNS maps the domain name to IP address whereas DHCP is a protocol which assigns IP to the hosts in a network be it statically or dynamically. DHCP is also used while setting up the DNS server to the host.

How does DHCP work with DNS?

Brief Introduction: DHCP and DNS. DHCP and DNS are two essential services in IT networks. While a DHCP server sends out information that clients need to communicate with other machines and services, DNS ensures that servers, clients, and services can be found by their names.

What is DHCP and why it is used?

Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automate the process of configuring devices on IP networks, thus allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP. DHCP is an enhancement of an older protocol called BOOTP.

What is the port number of DNS and DHCP?

Is DNS required for DHCP?

Like DNS server, it does not map domain names into IP addresses or IP addresses into domain names, DHCP server is used to configures the hosts mechanically.

Why would you use DHCP?

Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automate the process of configuring devices on IP networks, thus allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP.

Is DNS a network protocol?

The Domain Network System (DNS) protocol helps Internet users and network devices discover websites using human-readable hostnames, instead of numeric IP addresses.

What is default gateway IP?

Ad. In the networking world, a default gateway is an IP address that traffic gets sent to when it’s bound for a destination outside the current network. On most home and small business networks—where you have a single router and several connected devices—the router’s private IP address is the default gateway.

How do I configure DHCP?

Creating a DHCP Server

  • Go to Network > DHCP Server.
  • Click Add. The DHCP Server window opens.
  • Select an interface.
  • Click Next.
  • Select the network environment for the DHCP server. Option. Description.
  • Click Next.
  • Configure a static IP address for the adapter. Important:
  • Configure DHCP settings. Setting.

What is the purpose of DNS?

Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

What is DHCP example?

A DHCP-enabled client, upon accepting a lease offer, receives: A valid IP address for the subnet to which it is connecting. Some examples of DHCP options are Router (default gateway), DNS Servers, and DNS Domain Name.

Is DHCP a TCP or UDP?

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 BOOTP protocol. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client.
