Cisco CCNP / BSCI Test Tutorial: IP Version six Zero Compression
BSCI Test good results is all A part of becoming a CCNP, and Element of that good results is currently learning the basic principles of IP Model six, or IPv6. Among the most hard areas of learning IPv6 principles is definitely the radically distinct addressing plan that IPv6 employs as compared to IPv4. Just take a look at these sample addresses:
Typical IPv4 안전공원 address: 129.fourteen.12.two hundred
Usual IPv6 address: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you'll be able to see, IPv6 isn’t exactly just tacking two far more octets on to an IPv4 tackle!
I haven’t fulfilled too many networkers who really like typing, specially numbers. You’ll be delighted to find out there are some rules that will shorten Individuals addresses http://edition.cnn.com/search/?text=토토사이트 a little, and it’s a very good concept to get fluent with these policies on your exam.
You bear in mind from the CCNA reports that there’s no difference between an upper-situation letter and decreased-scenario letter in hexadecimal. That’s one among a few fundamental policies you need to know when dealing with IPv6 addressing. One other factors take care of every one of the zeroes you’ll run into in IPv6 addresses! One of such procedures is the rule of zero compression.
The rule of zero compression states that if an address incorporates consecutive fields of zeroes, they are often expressed with two colons. It doesn’t issue Should you have two fields or 8, you are able to only style two colons and that can symbolize all of them. The real key Here's that you can only do this when in an IPv6 address. This is referred to as zero compression. In this article’s an illustration:
Unique format: 1234:1234:0000:0000:0000:0000:3456:3434
Making use of zero compression: 1234:1234::3456:3434
Again, it's essential to bear in mind you'll be able to only do that when in an IPv6 deal with expression.
Let's say you'll find zeroes while in the handle that don’t quite fit this rule? The next A part of our IPv6 tutorial will cope with leading zero compression, A different Instrument You may use to shorten these long, extended addresses!
