You can activate this service for FREE through your control panel, for every domain you have at Papaki, having your domain used as custom domain for services such as blogger, Google Apps etc.

The DNS service translates a domain name into an IP, eg. the domain www.papaki.gr to the IP 194.219.114.194, which is necessary to every browser in order to connect to this site.

For example:

You have a blog with blogger, onoma.blogger.com, and you wish to open this Blog under your domain name, www.onoma.gr.

What you need to do is to activate the custom domain function of Blogger.

Then, you will be asked to create some DNS records, which you can easily create by activating the DNS hosting service for your domain onome.gr at Papaki. 

The DNS hosting service is free for all domain names you have at Papaki.

In a similar way, you can use more services, such as Google Apps and others, that support the custom domain usage!
