Under what circumstance would it be appropriate to use private IP address?

The usual reason to use private IP addresses is when you have to share a single public IP address (or a few public IP addresses) among a larger number of computers. Nowadays, this situation is quite common - it is no longer possible to assign a public IP (version 4) address to each and every computer; IP addresses are starting to get scarce. In the scenario mentioned above, private IP addresses according to RFC 1918 are used in combination with NAT (network address translation).


What is public ip and private ip address?

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets (local networks): 10.0.0.0 - 10.255.255.255172.16.0.0 - 172.31.255.255192.168.0.0 - 192.168.255.255Also, IP addresses in the range of 169.254.0.0 -169.254.255.255 are reserved for Automatic Private IP Addressing. These IP's should not be used on the Internet. I usually use 192.168.0.1, 192.168.0.2, etc. and a subnet mask of 255.255.255.0 when assigning static IP addresses to computers on a small Local Area Networks (LANs). If a DHCP server is also on the LAN it's scope (range of IP addresses that it can assign to computers on the LAN set to obtain their IP addresses automatically) should be adjusted so it does not interfere with locally assigned static IP addresses.


What do IP numbers represent?

An IP number is the unique address by which you can reach an individual computer. At least, that was the original idea of IP addresses; if you want to know how this has changed in recent days, do some research on the following topics: IP address exhaustion; private IP addresses; public IP addresses; NAT.

How many IP addresses must you obtain from your ISP in order for all five clients in your office to be able to access servers on the Internet?

How do you find someone name from IP address?

There are two types of IP addresses: public and private IP adresses. Private IP's are categorized into 5 classes ranging from A to E. Ever since the growth of tcp/ip networks, engineers have associated a name such as: Google with a public IP address. We accomplish this through DNS which primarily translates these names to IP addresses and vice versa. If you would like to look up the name of a public IP addresses or find it's registrar use the program WHOIS. For private IP addresses you would first have to be connected to the network then you would view your local DNS records.


Explain the need for NAT Router?

A NAT router (or other device with NAT) is often used to share Internet access, with a single public IP address, among an antire network. The point is, the public IP addresses (for IP version 4) are getting scarce.A NAT router (or other device with NAT) is often used to share Internet access, with a single public IP address, among an antire network.
