Cisco CCNP / BSCI Examination Tutorial: IP Edition six Zero Compression
BSCI exam achievements is all Component of starting to http://edition.cnn.com/search/?text=토토사이트 be a CCNP, and Element of that accomplishment is currently learning the basics of IP Version 6, or IPv6. Among the most tricky elements of Understanding IPv6 principles is the radically distinct addressing plan that IPv6 uses as compared with IPv4. Just evaluate these sample addresses:
Regular IPv4 tackle: 129.fourteen.12.200
Common IPv6 tackle: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you may see, IPv6 isn’t exactly just tacking two more octets on to an IPv4 tackle!
I haven’t achieved too many networkers who genuinely like typing, significantly numbers. You’ll be satisfied to learn there are numerous regulations that could shorten Individuals addresses a little bit, and it’s an excellent concept to get fluent Using these policies for your personal Examination.
You keep in mind out of your CCNA research that there’s no difference between an upper-case letter and lessen-situation letter in hexadecimal. That’s certainly one of three simple rules you have to know when dealing with IPv6 addressing. The other aspects cope with each of the zeroes you’ll run into in IPv6 addresses! A single of those regulations is definitely the rule of zero compression.
The rule of zero compression states that if an address incorporates consecutive fields of zeroes, they can be expressed with two colons. It doesn’t make any difference When you have two fields or 8, you may only type two colons and which will symbolize all of these. The key Here's you could only do that the moment in an IPv6 address. This is known as zero compression. Right here’s an illustration:
Unique structure: 1234:1234:0000:0000:0000:0000:3456:3434
Employing zero compression: 1234:1234::3456:3434
All over again, you have to understand that you'll be able to only do that once in an IPv6 deal with expression.
What if there are zeroes in the deal with that don’t 토토사이트 very suit this rule? The subsequent Section of our IPv6 tutorial will cope with main zero compression, Yet another tool you can use to shorten these extensive, lengthy addresses!
