Re: [PLUG] dig returns "Transfer failed", what to do?

| I really do disagree. Because I can leave off the left hand side,

I'm not sure why this confuses you. I see nothing confusing.

| @   IN  A     

the address (A) of '@' (aka '') is ''.
'' is an address.

the $TYPE of $LEFT is $RIGHT. $RIGHT is a $TYPE.

|     IN  MX	          100

the mail exchange data (MX) of '' is '100'.
'100' is mail exchange data.

the $TYPE of $LEFT is $RIGHT. $RIGHT is a $TYPE.

|     IN  NS    

the nameserver (NS) of '' is ''
'' is a nameserver.

the $TYPE of $LEFT is $RIGHT. $RIGHT is a $TYPE.

|     IN  NS    
|     IN  NS    
|     IN  NS    

| All of these RR types are descriptions of (expressed
| here ONLY as @, shorthand for the declared zone).

yes, that is correct.

| And if that doesn't convince you, what about the SOA record? That

convince me of what? that:
    | DNS terminology unfortunately DRASTICALLY misuses the word
    | "canonical", but that really is what the C in CNAME stands for

no, sorry. I am having trouble seeing the confusion.

        mail            CNAME

the canonical name (CNAME) of 'mail' is ''
'' is the canonical name.

the $TYPE of $LEFT is $RIGHT. $RIGHT is a $TYPE.
