    Is this in a Cisco class or did you post in the wrong forum? I only ask because DNS isn't a big Cisco subject...

    Anyway, you're going to need to be more specific with what you need help with. There's entire books dedicated to DNS. No one is going to be able to simply lay it all out for you in a post.

    Not true! Cisco people curse DNS every time they do a typo until they disable lookups ;)

    Read RFC1034 and RFC 1035 if you want to find out more about DNS.

    Yeah dude , this is the frist time it's being covered in CCNA but i did not realise how much detail it went to , it was easy in my A+ and Net + , but this just goes into so much detail , sorry i can't be more specific , because i don't have a clue about it.

    Are you talking about the different records that gets propagated such as web site and mail server records?Or the tree structure for DNS such . is the root DNS server then you have .com .gov, etc DNS servers and it branches from there.

    TonyDuffy,

    Is the overall Domain Name System one of the things you're confused with?

    Yeah , it's look the root with .gov .uk .com , etc , then underneath that and the isp providing it.

    Thing like that

    If you need help with the basics, start with Wikipedia: http://en.wikipedia.org/wiki/Domain_Name_System

    Move on to the RFCs that Tiersten posted once you want to get into the nitty-gritty material.
