Dear Ralston,"Starter" link:
Read carefully to ensure that the link does indeed fit/match your environment and configuration requirements.
If not, just use the link information to establish the applicable search criteria and then go online.
Details matter so keep the big picture in mind - be sure that you fully understand the current network configuration.
Plan out step-by-step what needs to be done. Then execute accordingly.
Hey Ralston,Not sure about the direction we are going here....
How many more addresses do you actually need?
Seems to be turning into a "homework" like question....
You know your network environment and the IP address requirements. What you now have, what you need, and the current IP address ranges subnet masks, etc...
My suggestion is to: 1) present what you now have and 2) post what you think needs to be done.
Need to plan out what is to be done and then how that will be done.
Hey Math Geek,sounds a lot like questions we are solving in my networking 101 class as well. i can't imagine anyone actually using a /21 or /22 network at home. a /24 is ample for any home environment (256 ip's) and a /16 (65,536 ip's) would be plenty enough for even a big office environment. going through all the work of converting from /21 to /22 (which is actually less ip's than before) seems like a theoretical homework question rather than a real world problem
but whether or not to use same server or new one for new subnet would depend on the current server. how busy is it serving all the ip's it does now? could it handle the workload of another large amount of ip's? at least that's what i would consider when deciding if i need a new server or not.
