=============================================== Detection of registered domains by reg-dom libs

The reg-dom libs are available in C, Perl and PHP so far.

They include recent representations of the effective TLD list available at https://publicsuffix.org/list/effective_tld_names.dat and help to convert an arbitrary domain name to the registered domain name.

Sample use: dkim-reputation.org blocks signing domains on the level of registered domains to rate senders who use e.g. a.spamdomain.tld, b.spamdomain.tld, ... under the most common identifier - the registered domain - finally. Project page: https://www.agitos.de/registered-domain-libs/ Updated library downloads: https://services.agitos.de/regdom-lib-downloads/

Pseudo code: registeredDomain = getRegisteredDomain(ingoingDomain);

Return values:

1. NULL if ingoingDomain is a TLD
2. the registered domain name if TLD is known
3. just . if is unknown This case was added to support new TLDs in outdated reg-dom libs by a certain likelihood. This fallback method is implemented in the last conversion step and can be simply commented out.

If you like to regenerate the effective TLD tree structure by yourself you can use the script generateEffectiveTLDs.php with the following parameters:

php generateEffectiveTLDs.php php > PHP/effectiveTLDs.inc.php php generateEffectiveTLDs.php perl > Perl/effectiveTLDs.pm php generateEffectiveTLDs.php c > C/tld-canon.h
