In the EU you have Directive 2006/24/EC:
http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2006:105:0054:0063:EN:PDF

Article 6 - Periods of retention
Member States shall ensure that the categories of data specified in Article
5 are retained for periods of not less than six months and not more than two
years from the date of the communication.

Article 5 - Categories of data to be retained
1. Member States shall ensure that the following categories of data are
retained under this Directive:
(a) data necessary to trace and identify the source of a communication:
(...) the name and address of the subscriber or registered user to whom an
Internet Protocol (IP) address, user ID or telephone number was allocated at
the time of the communication;

Each member state creates its own law, according to the directive. In
Portugal, you have to retain the data for one year.

Luís Marta.
