'\' doesn't work because there has to be some way to escape a single quote in a single-quoted literal, which is done - as usual - using a backslash.

BTW, I wouldn't know why using single quotes here should make a difference with respect to what the OP wants to achieve....

(As to the OP's problem, my suspicion is that Net::DNS is doing some escaping on its own — though I haven't verified it.)
