It builds the PSL as a Trie structure for efficient lookup, making it suitable for large-scale processing. The module comes bundled with a copy of the PSL so it works out of the box, though that data is from 2019-12-21.\n\nThe package supports several query modes: extracting the registrable domain (base domain), returning only the effective TLD, handling IDNA-encoded domains, ignoring wildcards for aggregation, and strict validation to reject domains with invalid TLDs. It exposes both convenience functions (get_public_suffix, get_sld, get_tld) and a PublicSuffixList class for finer control. However, the project is abandoned\u2014no releases or commits since late 2021\u2014so the bundled data will not reflect newly added public suffixes.","worth_installing":"Yes, if your domain processing needs are static or historical. The package has no dependencies, low install friction, and a stable API. However, do not use it if you require current public suffix data\u2014the bundled list is from 2019-12-21 and the project is abandoned. Use fetch() to pull the latest list at runtime, or consider an actively maintained alternative if freshness is critical."},"id":"publicsuffix2","links":{"html":"https://skillfed.io/packages/publicsuffix2","md":"https://skillfed.io/packages/publicsuffix2.md","pypi":"https://pypi.org/project/publicsuffix2/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2019-12-21","license_spdx":null,"license_treatment":"copyleft","name":"publicsuffix2","python_support":"unspecified","summary":"Get a public suffix for a domain name using the Public Suffix List.
