- These seem to be strings as described in RFC1035 4.1.4 and can be:
-
- - a sequence of labels ending in a zero octet
- - a pointer
- - a sequence of labels ending with a pointer
-
- A label is a byte where the first two bits must be zero and the remaining
- bits represent the length of the label followed by the label itself.
- Therefore, the length of a label is at max 64 bytes. Under RFC1035, a
- sequence of labels cannot exceed 255 bytes.
-
- A pointer consists of a 14 bit offset from the beginning of the data.
-
- struct ptr {
- unsigned ident:2; // must be 11
- unsigned offset:14; // from the beginning of data
- };
-
- This is used as a method to compress the packet by eliminated duplicate
- domain components. Since a UDP packet should probably be < 512 bytes and a
- DNS name can be up to 255 bytes, this actually makes a lot of sense.
