How do you assign or set an IP address for a device or an interface? /...... : .... There are two methods of assigning (setting) an IP address. (II Static setting: To use this method, someone has to log into the device and manually configure the IP address and subnet mask. The advantage of this methodis that the IP address will be fixed because it is statically configured on the device, the disadvantage is that it requiresInterface FastEthernet 0/0 ip address 10.0.0.2 255.255.255.0Dynamic address assignment: If there are hundreds or even thousands of devices that need to be assigned IP addresses, the static setup method will take a long time. In addition, if for some reason the network administrator needs to change the subnet mask or56 Chapter 1 Network Protocols and Network Device Basicsto manually configure it manually. This method of IP address assignment is commonly used for network devices or servers whose IP addresses are important and always remain the same. For example, you can execute the following command to assign an IP address to the F0/0 interface of a CiscoiOS router.If you adjust the network topology, the IP addresses of all devices may need to be reconfigured. Dynamic address assignment allows network devices to obtain IP addresses automatically. Dynamic address assignment can be performed with the help of Dynamic Host Configuration Protocol (DHCP), which allows network devices to automatically obtain IP addresses and other network configuration information. BOOTP can perform a similar function, and is no longer used because the protocol is older.This explores how DHCP works. /Sffl Defined in RFC2131 DHCP is a client server protocol that automatically provides W.vans various network configuration information to client devices. A DHCP server has a pool of IP addresses from which IP addresses can be assigned to client devices. IP addresses are not assigned to client devices in a static manner; the DHCP server only "leases" IP addresses to client devices for a period of time. When the lease period is approaching, the client device can request a lease renewal. In addition to IP addresses, the DHCP server can also provide other network configuration information.
