Hi Chris,

I'm not a fan of <dtml-sql> at all. I find it very hard to read and 
personally prefer to use straight SQL with DTML-ifs at the most.

Why not simply try
inet = <dtml-sqlvar a type="nb" optional>
client_hostname = <dtml-sql var b type="nb" optional>

I find it much easier to match the rendered SQL with what I want.
