Network address

[SONYFX]

If the network address of my home network is 192.168/16, how do I assign addresses to three computers in my network?

The number that you posted is not an IP number.

However you can either use the DHCP server (if you have a Cable/DSL Router) and let the server assign the numbers.

Or if you assign manually.

192.168.1.10 192.168.1.11 192.168.1.12 .... and so and so on.

In general 192.168.x.x 192.168.x.(x+1) 192.168.x.(x+2) 192.168.x.(x+3) ......

Nit...

Your formula implies that the fourth octet sequence has to begin at the same number as the third octet. Which isn't what you mean. How about...

192.168.x.y, 192.168.x.(y+1), 192.168.x.(y+2), ...

Isn't the usual number like this:

192.168.0.1

192.168.0.2

192.168.0.3.......

Is this arbitrary? Is there a specific meaning for address startgin with 192.168?

This is a "set" rule-of-tumb to avoid conflicts ... around the globe there are lot's of IPs give. For example, your ISP may give you an IP like 83.20.?.? (or something like that), a top DSN server (TLDs) will have another specific IP, ...

So to avoid conflicts, it's a set rule that private IPs should be set around 192.168.*.* ... that means you'll avoid conflict/missanderstandings (sp?) when managing IPs.

If your ISP gives you an IP 83.20.0.1 (for example), and you give your private network IPs in the range 83.20.0.1 - 83.20.0.100, it would be a real mess and it would potentially bring you big problems (if your network worked in the first place).

So hence the reason ...


<edit>
One more add ... if you ping localhost, you're pinging the local machine ... and what if you ping 127.0.0.1 ? Well, you're pinging the local machine too ... it's another "rule" that 127.0.0.1 points to the local machine. If you start giving IPs from 127.0.0.1 to 127.0.0.100 you'll begin having problems, specially with the 127.0.0.1 one (that is, if your operating system let's you set 127.0.0.* as an IP, in the first place).

IP is a global identifier, and as a global identifier, must have some "rules" or the global integration of networks would be a pain.

An easy way to explain Mac/IP Addressing. Your MAC address is like your Social Security number, It's 100% unique to you. The problem with that, is you cannot send mail to a SSN. So you have a postal address, If you read the address from the bottom up you get: Zip Code, City/State, Street, house number. IP is that way. You have network/node addresses xxx.xxx is the network (for class b) and the yyy.yyy is the node, or house of the address. Does this make sense?

 

[syco83]

the private ip address ranging should be
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0. - 192.168.255.255

Is this arbitrary? Is there a specific meaning for address starting with 192.168?

192.168.x.x means that the private band can start with 198.168. and the last two groups can be numbers between 0 - 255.

Why 0- 255? Because that is 256 number and 2 (binary math) by the power of 8 (8 bit) is 256.

So you can assign your Network with (example) 192.168.222.222

Arbitrary? Yes, and No. Yes because you can choose any scheme within the range. No because once you choose the range you have to conform with the rest of the rules.

In addition you should be aware that there is an External IPs given by the ISP, and it not your choice which number it is, and Internal IPs assigned to a Local Network that you can decide upon.
