Cisco CCNP / BSCI Exam Tutorial: IP Version 6 Zero Compression
BSCI exam accomplishment is all 메이저사이트 Section of turning out to be a CCNP, and A part of that accomplishment is now Finding out the basic principles of IP Variation 6, or IPv6. One of the more hard aspects of Finding out IPv6 concepts is definitely the radically unique addressing scheme that IPv6 makes use of in comparison with IPv4. Just examine these sample addresses:
Normal IPv4 tackle: 129.fourteen.twelve.200
Typical IPv6 address: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you are able to see, IPv6 isn’t specifically just tacking two extra octets onto an IPv4 tackle!
I haven’t satisfied a lot of networkers who really like typing, significantly quantities. You’ll be content to find out usually there are some guidelines that will shorten These addresses a tad, and it’s a very good thought to generally be fluent Using these guidelines for your personal Examination.
You try to remember from a CCNA experiments that there’s no distinction between an higher-circumstance letter and decrease-case letter in hexadecimal. That’s certainly one of 3 simple guidelines you need to know when working with IPv6 addressing. The other aspects manage all of the zeroes you’ll operate into in IPv6 addresses! A person of such regulations would be the rule of zero compression.
The rule of zero compression states that if an address is made up of consecutive fields of zeroes, they are often expressed with two colons. It doesn’t make any difference Should you have two fields or eight, you are able to https://en.search.wordpress.com/?src=organic&q=토토사이트 simply type two colons and that may signify all of these. The main element Here's you can only do this once in an IPv6 deal with. This can be known as zero compression. In this article’s an case in point:
Primary format: 1234:1234:0000:0000:0000:0000:3456:3434
Using zero compression: 1234:1234::3456:3434
All over again, you must bear in mind you are able to only make this happen the moment in an IPv6 deal with expression.
Imagine if you'll find zeroes inside the handle that don’t pretty fit this rule? Another Section of our IPv6 tutorial will handle primary zero compression, A further Software You can utilize to shorten these very long, extensive addresses!
