A private registration domain is most certainly worth it if you wish to increase anonymity on the web and operate a website with an extra layer of security. Having the option of hiding your personal contact details will help you to concentrate on building your business without having to deal with mountains of spam email or other unsolicited contact. Online threats may also be reduced as hackers will not be able to access your personal details.
A private domain is also worth it if you currently use one of the supported TLDs which are: .com, .net, .org, .biz, .info, .mobi, .name, .cc, .tv, .london and .wales. If your website is already associated with one of these domains, then transferring to a private domain registration on renewal is simple. All you need to do is access the IONOS Control Panel and click the 'manage domains' tab. From here you can follow the 'edit domain settings' link and proceed to update your settings. Once you have selected the 'private' option, please wait around 24 hours until WHOIS updates the information in its database.
