Cisco CCNP / BSCI Examination Tutorial: IP Variation 6 Zero Compression
BSCI Examination achievement is all Portion of turning out to be a CCNP, and Portion of that accomplishment is currently http://edition.cnn.com/search/?text=토토사이트 Discovering the basics of IP Edition 6, or IPv6. One of the most hard aspects of Studying IPv6 principles would be the radically distinct addressing scheme that IPv6 makes use of in comparison with IPv4. Just evaluate these sample addresses:
Normal IPv4 handle: 129.14.12.two hundred
Regular IPv6 deal with: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you may see, IPv6 isn’t particularly just tacking two additional octets on to an IPv4 deal with!
I haven’t satisfied a lot of networkers who truly like typing, specially quantities. You’ll be joyful to find out usually there are some rules that should shorten All those addresses a bit, and it’s an excellent concept being fluent Using these rules for the Examination.
You bear 메이저사이트 in mind from your CCNA scientific studies that there’s no distinction between an higher-case letter and reduce-scenario letter in hexadecimal. That’s amongst 3 fundamental regulations you need to know when working with IPv6 addressing. Another variables take care of each of the zeroes you’ll operate into in IPv6 addresses! One particular of these regulations may be the rule of zero compression.
The rule of zero compression states that if an handle has consecutive fields of zeroes, they may be expressed with two colons. It doesn’t issue For those who have two fields or 8, you can simply just form two colons and that can symbolize all of them. The important thing Here's that you can only try this the moment within an IPv6 deal with. This is certainly called zero compression. In this article’s an example:
First structure: 1234:1234:0000:0000:0000:0000:3456:3434
Making use of zero compression: 1234:1234::3456:3434
Yet again, you have to remember that you can only try this once within an IPv6 handle expression.
Let's say there are actually zeroes while in the tackle that don’t rather in good shape this rule? Another Section of our IPv6 tutorial will handle top zero compression, A further tool you can use to shorten these prolonged, extended addresses!
