It is a protocol used for assigning IP's to the host in a local area network statically or dynamically.
Dynamic Host Configuration Protocol (DHCP)
Consequently, it "is present in a lot of home routers and certain Internet of Things gadgets"  and is included in Android. It can serve the names of local machines which are not in the global DNS. This can quickly evolve to a local ad blocker when combined with adblocking site list providers. If done on a router, one can efficiently remove advertising content for an entire household or company. From Wikipedia, the free encyclopedia. Free and open-source software portal.

DHCP and DNS: What Are They, What’s Their Difference?
Computer networking terminology consists of a vast array of acronyms and abbreviations, and many users often confuse two three-letter terms that each begin with the same letter: DNS and DMZ. While one of these networking terms helps your computer identify destinations for outbound traffic, the other helps inbound traffic reach a host on your network. DNS, the recognized abbreviation for Domain Name Service, is the technology that helps a computer identify remote hosts in human-friendly terms. Computers on the Internet identify themselves to one another with a series of three-digit numbers grouped together into an Internet Protocol address, or IP address. When you enter a Web address in your computer browser, though, you likely enter a series of words followed by a suffix like. This human-friendly address is known as a domain name.
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. The Dynamic Host Configuration Protocol dynamically assigns IP addresses and other configuration options to devices in a network. This is why DHCP is great for larger networks with constantly changing clients, e. The DHCP server either distributes free IP addresses from a specific pool, or it assigns static addresses to the clients and identifies them via their MAC address Media Access Control, unique identifier assigned to a network interface controller. In the first scenario, the clients can get different IPs, which can be convenient if the server hands out addresses from a small pool to a large number of devices that are not active at the same time.
The DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) are both created to make it easy for us to use networks or.
Dynamic Host Control Protocol (DHCP)/Domain Name System (DNS)
Without DHCP, IP addresses for new computers or computers that are moved from one subnet to another must be configured manually; IP addresses for computers that are removed from the network must be manually reclaimed. With DHCP, this entire process is automated and managed centrally. 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. The DHCP server stores the configuration information in a database that includes:. Valid IP addresses, maintained in a pool for assignment to clients, as well as excluded addresses.

I architect and build software systems. Living in Germany. The subject of networking, unfortunately, is boring for the most of our colleagues. All the used technologies, protocols and best practices are pretty old, they have been surrounding us and ensuring the communication between millions of devices around us for a long time. Even programmers most often take networks for granted and don't think about how they work.
The CCNA exam includes the following topics that we will explore in detail:. It is also a client-server application that maintains and provides access to DNS records. Many Internet services, such as web browsing and email delivery, rely on DNS service.
DHCP is a network protocol that is used to assign various network parameters to a device. This greatly simplifies administration of a network, since there is no need to assign static network parameters for each device. DHCP is a client-server protocol. A DHCP server can also provide some other parameters, such as:. The client responds by broadcasting a DHCP Request packet, requesting the network parameters from the server that responded first.
