Cisco Ccnp / Bsci Exam Tutorial: Internet Protocol Address Version 6 Zero Compression

BSCI assessment success is all part of becoming a, and part of this success has become studying the basic principles of IP Version 6, or IPv6. One of the most challenging areas of learning IPv6 methods is the radically different addressing scheme that IPv6 uses as compared to IPv4. Just look at these sample addresses:

Standard IPv4 address: 129.14.12.200

Standard IPv6 address: 1029:9183:81AE:0000:0000:0AC1:2143:019B

IPv6 isn't exactly just tacking two more octets onto an IPv4 target, as you can view!

I've not met too many networkers who love writing, specially figures. You'll be happy to know there are several rules that'll limit these handles a bit, and it is a good idea to be fluent with one of these rules for your test.

You remember from your own CCNA studies that there surely is no difference between an letter and lower-case letter in hexadecimal. That is among three basic rules you'll need to learn when working with IPv6 addressing. The other facets handle all the zeroes you'll run into in IPv6 details! One of these principles is the principle of zero pressure.

The concept of zero compression states when a target contains consecutive areas of zeroes, they could be expressed with two colons. It doesn't matter if you have two areas or ten, colons can be simply typed two by you and that'll represent all of them. The key listed here is as you are able to only do this once in an IPv6 address. That is called zero compression. Listed here is an example:

Initial format: 1234:1234:0000:0000:0000:0000:3456:3434

Using zero compression: 1234:1234::3456:3434

Again, you must understand that you can only do this once in an IPv6 address term.

Imagine if you can find zeroes in this rule that wasn't quite fit by the address? The following element of our IPv6 training will handle leading zero pressure, another tool you should use to limit these long, long addresses!
