Cisco CCNP / http://edition.cnn.com/search/?text=토토사이트 BSCI Test Tutorial: IP Edition six Zero Compression
BSCI exam achievements is all Component of getting a CCNP, and part of that results is now Mastering the fundamentals of IP Model 6, or IPv6. The most tricky elements of Studying IPv6 concepts is definitely the radically various 안전공원 addressing scheme that IPv6 uses in comparison with IPv4. Just have a look at these sample addresses:
Typical IPv4 handle: 129.fourteen.12.200
Standard IPv6 deal with: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you are able to see, IPv6 isn’t exactly just tacking two far more octets on to an IPv4 deal with!
I haven’t satisfied a lot of networkers who actually like typing, particularly figures. You’ll be delighted to be aware of there are many policies that may shorten those addresses a tad, and it’s a very good idea being fluent Using these policies for the Test.
You keep in mind out of your CCNA scientific studies that there’s no distinction between an higher-situation letter and decreased-scenario letter in hexadecimal. That’s considered one of 3 fundamental policies you need to know when dealing with IPv6 addressing. Another things manage the many zeroes you’ll operate into in IPv6 addresses! A person of those principles is definitely the rule of zero compression.
The rule of zero compression states that if an address is made up of consecutive fields of zeroes, they may be expressed with two colons. It doesn’t make any difference if you have two fields or eight, it is possible to only variety two colons and that should stand for all of these. The real key Here's which you could only try this the moment within an IPv6 deal with. This is often generally known as zero compression. Right here’s an case in point:
First format: 1234:1234:0000:0000:0000:0000:3456:3434
Working with zero compression: 1234:1234::3456:3434
Once more, you must take into account that you may only do that as soon as within an IPv6 tackle expression.
Let's say you'll find zeroes in the deal with that don’t rather in shape this rule? The next Element of our IPv6 tutorial will manage primary zero compression, Yet another Software You need to use to shorten these long, long addresses!
