Cisco CCNP / BSCI Exam Tutorial: IP Version six Zero Compression
BSCI Examination results is all A part of turning out to be a CCNP, and Element of that good results has become Studying the fundamentals of IP Version 6, or IPv6. One of the more complicated areas of Studying IPv6 ideas would be the radically diverse addressing plan that IPv6 makes use of when compared with IPv4. Just look at these sample addresses:
Usual IPv4 deal with: 129.14.12.two hundred
Usual IPv6 deal with: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you may see, IPv6 isn’t specifically just tacking two more octets onto an IPv4 tackle!
I haven’t met too many networkers who truly like typing, specially quantities. You’ll be delighted to understand there are some principles that may shorten Those people addresses a tiny bit, and it’s a very good strategy https://en.wikipedia.org/wiki/?search=토토사이트 being fluent Using these rules in your exam.
You don't forget from the CCNA scientific studies that there’s no distinction between an higher-case letter and decrease-situation letter in hexadecimal. That’s considered one of three primary regulations you need to know when dealing with IPv6 addressing. The other aspects contend with each of the zeroes you’ll operate into in IPv6 addresses! One particular of these rules is the rule of zero compression.
The rule of zero compression states that if an tackle consists of consecutive fields of zeroes, they are often expressed with two colons. It doesn’t make a difference When you've got two fields or 8, you are able to merely form two colons and that may stand 토토사이트 for all of them. The real key Here's which you can only do that the moment in an IPv6 deal with. That is referred to as zero compression. Listed here’s an illustration:
Initial format: 1234:1234:0000:0000:0000:0000:3456:3434
Utilizing zero compression: 1234:1234::3456:3434
Once again, you will need to understand that you'll be able to only do this at the time within an IPv6 tackle expression.
Imagine if you can find zeroes inside the tackle that don’t rather suit this rule? The subsequent Component of our IPv6 tutorial will deal with top zero compression, An additional Instrument You should use to shorten these extensive, extended addresses!
