It depends on the domain name you're trying to match.
Suppose you're looking up www.domain.org
There's a binary value immediately before each part of the name you're
resolving (www, domain, and org), which is the number of characters in that
part of the name.
Therefore in this case the string is: 0x03 w w w 0x06 d o m a i n 0x03 o r g
If you were resolving lists.netfilter.org it would be:
0x05 l i s t s 0x09 n e t f i l t e r 0x03 o r g
