DHCP uses a well-known UDP port number 67 for the DHCP server, and the UDP port number 68 for the client. Domain Name Service (DNS) Automatic Private IP Addressing (APIPA)
Hi I need your advise if we can provide proxy ip address and port number through DHCP server that is configured on Cisco routers and switches to our users or it isn't doable and better to relay the DHCP to a windows DHCP server that could do this The DHCP server transmits responses to the DHCP clients at a port number one greater than the UDP port specified. For example, if the default port 67 is used, the server listens on port 67 for requests and responds to the client on port 68. The DHCP server responds by sending a DHCPOFFER packet. In the IP section of the capture excerpt below, the Source address is now the DHCP server IP address, and the Destination address is the broadcast address 255.255.255.255. The DHCP section identifies the packet as an Offer. port number 137 is used for BIOS Name service, 138 for NetBIOS-dgm, 139 for NetBIOS Datagram service: 22: Used for SSH remote login protocol, SSH is short form of Secure Shell: 67, 68: The port number 68 is used for DHCP client and 67 is used for DHCP server : 53: DNS (Domain Name System) 69: TFTP (Trivial File Transfer Protocol) 70: Gopher
UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client. DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement.

Dec 15, 2010 · DHCP (Dynamic Host Configuration Protocol) is a service running on port number 67 which assigns IP addresses to computers in a network.Setting up a DHCP server requires you to specify a range of IP addresses which will be assigned to the computers on the network, a gateway address which is the address of the router or modem and a DNS server address which will be used to resolve hostnames. DHCP uses a well-known UDP port number 67 for the DHCP server, and the UDP port number 68 for the client. Domain Name Service (DNS) Automatic Private IP Addressing (APIPA) Oct 22, 2018 · DHCP server assigns IP addresses automatically to the devices when they connect to the network. In other words, DHCP server allows dynamic IP addressing. This is the main difference between DNS and DHCP server. Port Numbers. Port number is another difference between DNS and DHCP server. DNS uses port number 53 whereas DHCP works on port number
