FAQ
Does it support suffixes like .co.uk or .com.cn?
It handles common public-suffix patterns for quick hostname hierarchy checks. Edge cases should still be verified against the public suffix list.
Can it parse internationalized domain names?
It accepts common Unicode domain input. For xn-- forms, pair it with a Punycode converter.
