18 IP
IP (Internet Protocol) is an identifier for a computer or device on a TCP/IP network. Networks
using the TCP/IP protocol route messages based on the IP address of the destination. The format
of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each
number can be zero to 255. Example: 10.5.25.180.
Every computer that communicates over the Internet is assigned an IP address that uniquely
identifies the device and distinguishes it from other computers on the Internet. Within an isolated
network, IP addresses can be assigned at random as long as each one is unique. However, to
connect a private network to the Internet, the registered IP addresses must be used (called
Internet addresses) to avoid duplicates. The four numbers in an IP address are used in different
ways to identify a particular network and a host on that network.
Four regional Internet registries -- ARIN, RIPE NCC, LACNIC and APNIC -- assign Internet
addresses from the following three classes.
Class A - supports 16 million hosts on each of 126 networks
Class B - supports 65,000 hosts on each of 16,000 networks
Class C - supports 254 hosts on each of 2 million networks
The number of unassigned Internet addresses is running out, so a new classless scheme called
CIDR (Classless Inter-Domain Routing) is gradually replacing the system based on classes A, B,
and C and is tied to adoption of IPv6.
The list of CLI commands for the configuration of IP is as follows:
ping
ip route
ip routing
ip default-ttl
arp timeout
arp – ip address
ip arp max-retries
show ip traffic
show ip route
show ip arp
