Before you connect

Questions about psl.

The practical details behind the request, access and result.

Can Public Suffix Extractor handle complex TLDs like .co.uk?

Yes. It uses the official Mozilla list to correctly identify multi-part suffixes.

How does Public Suffix Extractor help with data cleaning?

It normalizes URLs so your agent can group traffic by the true root domain.

Will Public Suffix Extractor identify AWS buckets?

Yes. It recognizes them as cloud suffixes so you can filter them out of your results.

Is Public Suffix Extractor accurate for international domains?

It is 100% accurate because it uses the same list as major web browsers.

Can I use Public Suffix Extractor to find subdomains?

Yes. It separates the subdomain from the registrable domain for you.

Why can't I just split the domain by dots?

Because TLDs like .co.uk, .com.br, and .org.au have multiple parts. Splitting by dots would incorrectly identify the root domain. The PSL has 9,000+ entries.

Does it handle cloud provider domains?

Yes. Domains like *.amazonaws.com, *.azurewebsites.net, and *.cloudfront.net are in the PSL and handled correctly.

Can I pass a full URL with protocol and path?

Yes. The engine automatically strips the protocol (http/https), path, and query parameters before parsing.
