Cisco CCNP / BSCI Exam Tutorial: IP Variation six Zero Compression
BSCI Examination success is all A part of getting 메이저사이트 to be a CCNP, and Element of that achievement is currently learning the fundamentals of IP Edition six, or IPv6. Among the most complicated portions of learning IPv6 ideas is definitely the radically distinctive addressing plan that IPv6 employs compared to IPv4. Just evaluate these sample addresses:
Usual IPv4 address: 129.fourteen.12.two hundred
Common IPv6 deal with: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you may see, IPv6 isn’t specifically just tacking two additional octets onto an IPv4 handle!
I haven’t met a lot of networkers who really like typing, specifically quantities. You’ll be joyful to be aware of there are several rules that could shorten These addresses somewhat, and it’s a very good idea for being fluent with these procedures on your Examination.
You keep in mind from your CCNA reports that there’s no difference between an upper-circumstance letter and decreased-scenario letter in hexadecimal. That’s one of a few primary procedures you have to know when dealing with IPv6 addressing. The other variables cope with every one of the zeroes you’ll run into in IPv6 addresses! A person of such procedures may be the rule of zero compression.
The rule of zero compression states that if an handle contains consecutive fields of zeroes, they may be expressed with two colons. It doesn’t make a difference if you have two fields or eight, you may merely style two colons and that should signify all of these. The crucial element Here's which you could only make this happen when in an IPv6 address. That is often called zero compression. Here’s an case in point:
Authentic structure: 1234:1234:0000:0000:0000:0000:3456:3434
Using zero compression: 1234:1234::3456:3434
Yet again, you have to understand that you'll be able to only try this the https://www.washingtonpost.com/newssearch/?query=토토사이트 moment in an IPv6 tackle expression.
Let's say there are zeroes within the tackle that don’t rather match this rule? The following Section of our IPv6 tutorial will contend with main zero compression, A different Resource You should use to shorten these extensive, very long addresses!
