Cisco CCNP / BSCI Exam Tutorial: IP Version 6 Zero Compression
BSCI exam success is all part of becoming a CCNP, and part of that success is now learning the basics of IP Version 6, or IPv6. One of the most difficult parts of learning IPv6 concepts is the radically different addressing scheme that IPv6 uses as compared to IPv4. Just look at these sample addresses:
Typical IPv4 address: 129.14.12.200
Typical IPv6 address: 1029:9183:81AE:0000:0000:0AC1:2143:019B
As you can see, IPv6 isn’t exactly just tacking two more octets onto an IPv4 address!
I haven’t met too many networkers who really like typing, particularly numbers. You’ll be happy to know there are some rules that will shorten those addresses a bit, and it’s a very good idea to be fluent with these rules for your exam.
You remember from your CCNA studies that there’s no difference between an upper-case letter and lower-case letter in hexadecimal. That’s one of three basic rules you need to know when working with IPv6 addressing. The other factors deal with all the zeroes you’ll run into in IPv6 addresses! One of these rules is...
