What ports does DHCP use?
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). UDP port number 67 is the port used by the server, and UDP port number 68 is used by the client.
Where is DHCP server located?
DHCP Server Location
On home networks the DHCP server is on the home router or home hub. Most home routers will have the DHCP server enabled by default (turned on). However you can use another computer e.g raspberry pi as a DHCP server, but it is generally not done.
DNS, or the Domain Name System, translates human readable domain names (for example, www.amazon.com) to machine readable IP addresses (for example, 192.0. 2.44).
