And im talking the whole nine yards.. not just determining what class and that baby shit That shit is kinda complicated and depending on how questions are asked as far as how many hosts or network subnets can be obtained from an ip address is crazy. Aside from using an app, does anyone even work with this stuff in the "field"?? Or do they just use a subnetting calc app to simplify things? We went over some testout questions and they were pretty easy, but if you dont take your time you fuck up easily. Im a little over halfway from getting my associates and i kinda plan on continuing with my bachelors. Am i on track or is this something i shoulda learned a long time ago? With all the gen ed classes out of the way we are finnally getting a chance to work with cisco switches and routers and shit which is cool. I'm finnally feeling like im learning something useful.
