The entire hostname has a maximum of___________________?
Correct answer: A. 255 characters
- A. 255 characters
- B. 127 characters
- C. 63 characters
- D. 31 characters
Explanation
A complete DNS hostname may contain up to 255 characters or octets, although each individual label within it is limited to 63 characters. The 63-character limit therefore applies to a label, not the entire hostname.
