You may already know that IP addresses are unique identifiers that are assigned to devices that access computer networks. An IP address is a string of numbers separated by periods, which looks like this: 192.168.1.1. But IP addresses are actually abstract, logical identifiers, not physical locati...
An IP address identifies a device on the global internet, acting as the device's logical address to identify its network connection. Typically, an ISP assigns the IP address to a customer's device. Network administrators use DHCP to assign and manage IP addresses within the...
Logical address.IP address. Hostname.Useful for humans to recognize the device. A workstation has three identities: hostname, IP address and MAC address. In the case of IPv4 addresses, each host has a unique IP address on the network, and nodes rely on it to exchange information. Data br...
IPv4 address classes The Internet Protocol's local address space is split into five logical classes or ranges of IP addresses, each represented by a letter of the alphabet. ClassStart addressEnd addressNumber of networksIP addresses per networkTotal IP addresses availableSubnet mask ...
Logical IP address:It is assigned by the software inside a server or router and may or may not change periodically. For instance, your laptop can have a different IP address if you connect it to another hotspot. Physical IP address:Every hardware unit is built with a unique IP address that...
This number represents the device and must be unique within the network to avoid address conflicts. Each device on a network segment must have a unique address.IPv4 address classesThe Internet Protocol's local address space is split into five logical classes or ranges of IP addresses, each ...
If no router ID is configured, the loopback interface with the largest IP address is selected as the router ID. If no loopback interface is configured, the largest physical interface IP address will be used as the router ID. If the OSPF process is running, the router ID does not take ...
If a location is specified, only the interface entries in the specified location are displayed. Cisco IOS XR software allows conflicting IP address entries at the time of configuration. If an IP address conflict exists between two interfaces that are active, Cisco ...
Physical and logical interface addresses based on interface attributes The preceding IPv6 addresses can be configured on the same interface of the device. In this case, the system must select a source address or a destination address from multiple addresses on the interface. If the system supports...
This command is most useful on computers that are configured to obtain an IP address automatically. This enables users to determine which TCP/IP configuration values have been configured by DHCP, Automatic Private IP Addressing (APIPA), or an alternate configuration. If the name you supply for ...
