.it domain names have a duration of a year, which:
- starts from the registration of the domain name;
- or from the date of the last change (e.g. a domain name registered on 30 June 2013 for PAPERINO-REG and then transferred on 1 February 2014 to TOPOLINO-REG. expires on 1 February 2015).
The maintenance service of the domain name is tacitly renewed from year to year, unless rescinded, the request for which must arrive at the Registry within 15 days following the annual expiry.
You are strongly advised to keep a close check on the duration of the contract you have established with your ISP.
