This package contains a lightweight domain parser using the Public Suffix List (PSL) ICANN section based on the excellent work by Jeremy Kendall. WARNING: Some people use the PSL to determine what is a valid domain name and what isn't. This is dangerous, particularly in these days where new gTLDs are arriving at a rapid pace, if your software does not regularly receive PSL updates, because it will erroneously think new gTLDs are not valid. The DNS is the proper source for this in normal condition. If you must use it for this purpose, please do not bake static copies of the PSL into your software with no update mechanism.
