DHCP servers primarily assign IP addresses to devices on a network dynamically, but they can also associate hostnames with those IP addresses. When a device requests an IP address, the DHCP server can provide a hostname based on the client's request or the server's configuration. However, the primary function of a DHCP server is to manage IP address allocation rather than hostname resolution, which is typically handled by DNS servers.
IP addresses are assigned by DHCP servers, not by routers. DHCP servers will cache your IP address and reassign the same IP until the cache is cleared. ----
DHCP can assign IP addresses dynamically, but servers, including print serves, should have static IP addresses to avoid surprises.
They are network services that are always on listening on the network for requests. Example: DNS, DHCP ..... DNS resolves Domain Names to IP addresses. DHCP assigns dynamic IP addresses.
A DHCP server assigns the computer the IP address, while the DNS servers are responsible for providing names and lookup addresses when a computer requests the IP address of a hostname.
The components of DHCP (Dynamic Host Configuration Protocol) include the DHCP server, which assigns IP addresses and configuration settings; the DHCP client, which requests and receives these settings; and the DHCP relay agent, which facilitates communication between clients and servers on different subnets. Additionally, the protocol relies on a database to track assigned IP addresses and lease times, ensuring efficient management of IP address allocation.
DHCP Dynamic Host Configuration Protocal
To properly track hosts in a network using Dynamic Host Configuration Protocol (DHCP), the active scan setting known as "DHCP Snooping" should be enabled. This feature helps prevent unauthorized DHCP servers from providing IP addresses and ensures that only valid DHCP responses are processed. By maintaining a trusted database of IP addresses and corresponding MAC addresses, DHCP Snooping enhances network security and improves the accuracy of IP address tracking.
Often it is the server that is hosting the DHCP, so it can not assign its own address. But usually its just useful if the servers always have the same IP address. For example if a server is hosting a DNS server (as company servers often do), and all the workstations in the company are looking to that IP address for DNS info, the IP addrss can not change. If the IP address of the DNS server were to change then no computers on the network would be able to resolve domain names.
It's up to you. People usually have different ip addresses for gateways and DNS/DHCP servers. It's because a separate server is used for gateway.
Yes, a LAN could have two DHCP servers, but it wouldn't make much sense. Typically each LAN has it's own DHCP server or uses a DHCP relay agent to get an address from another subnet.
See related link. You can use MyLanViewer and detect DHCP servers.
yes DHCP require the authorization of the dhcp server before IP addresses can be allocated because until we authorize DHCP server the network does not know who is the dhcp server for the subnet. The DHCP server broadcasts the information to all.
