Dynamic Host configuration Protocol different IP address every time it connect to the network (How to work DHCP server):-
It Provide IP address in any system in the follwing four step :-
1) Dynamic Host Configuration protocol Lease Request.
2) Dynamic Host Configuration Protocol Lease Offer.
3) Dynamic Host Configuration Protocol Lease Selection.
4) Dynamic Host Configuration Protocol Lease knowlegment.
1) Dynamic Host Configuration Protocol Lease Request :- At first client prepare a packet and broadcast from searching the Dynamic host configuraiton protocol server.
2) Dynamic Host Configuration Protocol Lese Offer : Now the Dynamic host configuration protocol server select the internet protocol address from the scope the give the offer to the clients ,if more than one dhcp server if present in network than the dhcp server in which offer come enough first basic provide ip address.
APIPA(Automatic Private ip Addressing ) : In case DHCP server not ip addressing provide so this situation by APIPA ip address provide from clients side It range the IP address 169.254.0.1 to 169.255.254 in this case the client which broadcast massanger at first time will take specific IP from APIPA after this it always contect every five minutes to any Dynamic host configuration protocol server.
3) Dyniamic Host Configuration Protocol : When client take the offer then the Dynamic host configuration protocol server send the selected IP address from the client.
4) Dynamic Host Configuration Protocol : After giving the IP address given the server send massage Dynamic host configuration protocol client.
The "Rosa process" in DHCP does not appear to be a recognized term within standard networking protocols. If you meant "DHCP process," it involves the dynamic allocation of IP addresses and other network configuration parameters to devices on a network. This process typically includes four stages: DHCP Discover, DHCP Offer, DHCP Request, and DHCP Acknowledge (DORA), allowing clients to request and receive IP addresses from a DHCP server effectively. If "Rosa process" refers to something specific outside standard DHCP terminology, please provide more context for clarification.
The port 67 and port 68 are used by DHCP and the DHCP clients.
dhcp has to be authorized
The use of a DHCP relay agent is an agent that relays DHCP between DHCP clients and DHCP servers on different IP networks. The DHCP relay agent is compliant with RFC 1542.
router (config)# ip dhcp servicerouter (dhcp-config)# ip dhcp pool router (dhcp-config)# network
(DHCP) Dynamic host Configuration Protocol. The Default Port Number is: for DHCP client : 546 for DHCP server : 547
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.
yes because it works on DHCP principle..the subnet needs to be configured for it
Those are the four phases of acquiring an IP address via DHCP. More information would be needed to indicate which of the 4 phases are being used at this point.
dhcp-client
DHCP server configuration in /etc/dhcp/dhcpd.conf(FEDORA)or /etc/dhcpd.conf (RHEL).
DHCP V6 works on SARR process where:- S=SOLICIT message using multicast A=Advertise message form sever side R=Request R=Reply because ipv6 does not support broadcast. VIMAL KUMAR SINGH
