Subnetting

Are there any online tutorials that teach subnetting? The sheet i've got is, lets say not human freindly

Thanks a lot

What do you need to know? Isn't there something in the sticky above?

Simplest way I look at subnetting is to work in Binary. Then it is real simple.

Thanks MAllan. I found a really supurb site that explains it in simple steps:

Brilliant site

Site looked interesting... but it would help if he would learn how to create a website. Seeing old warnings about "IE 6.0 or Netscape 7.0" is annoying for us Opera and Firefox users when big chunks of the site fail to display....

As to subnetting - are you learning this for a course? For splitting up an office network? Or just for curiosity? If it's the latter.... then just use the Class C defaults of 255.255.255.0 to keep life simple.

Cisco CCNA MAllen. The wise crack teachers seam to assume a lot. They assumed we would know how to do it :confused:

Furthermore they gave us a three router lab to do. They asumed we knew what to do. Once again, :confused:

tbh its similar to us, but we havent had any practical experience with subnetting and the other server features on server 2003. it would help loads if we did say even a hour of good teaching on it, problem is they expect us to wipe our home machines to play about with it, and i would but i dont have a second machine really, and there is little point in trying to setup a network with one machine!

Exactly mate! And all they ever do is "Okay so you're in class. Good. Open up the curriculum and go go go!"

So all of us are looking at each other "Aren't you going to teach us?"

lol yea, i've got a 100 page report based on a case scenario. to be done for next thursday i've got 12 pages

basically about 20 windows 98 workstations and 1 NT4 server currently, with only file storage and email on the server, and a slow 56k connection, and we have to upgrade it for £20,000. but now he provided us with a change in requirements £15,000 and vpn access to the work for a sales department... man this isnt easy specially when you havent done a lot of the stuff practically before.

Hiya.

Understanding TCP/IP subnetting is a pre-requisite for CCNA nowadays, especially since they've amalgamated the 2 courses into one and it's a 5 day'er. Pick up the IP Subnet Calculator from the web (google for it) and use it to check the results.

The best bet with subnetting (until you get to know it better) is to look at it all in binary, as has been suggested. It will get better, trust me, and soon you'll be able to quote entire subnets just from an IP address and slash notation, it just takes practice.

so whats your course called?? as up here it was SGA Computing then its HNC (2nd year) and the third year (HND) then its onto a degree with a university.

Ricochet J · 17 Feb 2006 at 16:35

The course is called Cisco CCNA. Its split into 4 semesters. I thought you were doing it too. Once you've completed the course and passed you get a CCNA qualification which stands for "Certified Cisco Network Associate". Sounds fancy eh?
I've seen some people put it beside thier names too

e.g. John Smith (CCNA)

sja360 · 17 Feb 2006 at 16:50

i though the cisco courses we're all like MS one's either its a few weeks of hard graft etc, instead of full on 4 years of it. how much does it cost for you doing the course?

Ricochet J · 17 Feb 2006 at 18:10

Nope. The Cisco course is as long as you want it to be. Ideally the course is two years, and 2 semesters in each year hence 4 semesters. Therefore semesters 1 and 2 in year 1 and semesters 3 and 4 in year 2. And the reason its in semesters is because its an American course. :rolleyes:

But like I said earlier. If you want to push yourself and do it in half a year fine. But if you want to take your time and do it over 2 years like me its also okay. However you only pay for a certain number of hours of learning from an instructor, like 152 hours or something which obviously means you cannot do it over like 7 years or something silly like that

The course price is around £3000. You can pay for the whole course or break it down and pay in semesters or can just pay for the final exam and teach your self. I think the final exam is something like £250 if you only want to pay for that. But I get my Cisco course free because I choose it as a course for my college options.
So in college i'm doing A levels:
Mathematics
Physics
Graphics
General Studies
And qualification Cisco CCNA

However if you were to do it externally you would have to pay for the course.

Hope that clarifies things
