But we quickly realized, as the Internet took off, that there were a number of problems with using classful IP addressing and it actually led to us quickly running out of IP addresses. So we came up with a few different solutions to help us get out of this problem and one of them is the use of classless inter-domain routing. Or CIDR, which is sometimes pronounced sy-der, some people say sid-der, and I also even hear people say see-der. Whatever you call it, it's CIDR or classless inter-domain routing. So, let's talk about these problems. When we had classful IP addressing, we had our A, B and C class addresses and the difference between them with just too large. You know, you had a class A range which had almost 17 million IP addresses, you had your class B ranges that had a little over 65,000 addresses…
