A quick sql query and then a fixdns script should do the trick.
It's all encrypted inside database !
Yes I have run into that as well.
My plan for attack of this issue would be:
Custom script calling in kloxo includes,
loop through database
use lxadmin functions to decrypt data
regex ip replacement or simple string replace may be enought
function to encrypt
replace data
loop until done with domains
I have not researched this issue spacedust, but that is how I would write a quick fix for your problem - you must remember: if kloxo encrypts it, it can decrypt it. I do not know these functions and would have to do more scouring through code.
I know that doesn't help much, but it may give you some direction.
