Using your own nameservers has the advantage of letting you change entries in the zones on a more flexible basis. Plus it is free of charge. However, you need to already have basic knowledge on how to administer your own nameservers.
Important: Most registrars require you to have at least two nameservers, and in some cases, their IP addresses need to be in different subnets.
You can test the nameservers configuration by using tools such as dig or nslookup in Windows. If you accidentally made a mistake while you were configuring the zone, the Registry check will fail.
To use your own nameservers for .com, .net, .org, .info, .biz, and .eu domains, you need to first register the nameservers: menu item Domains -> My Domains, choose your domain, click Private Nameservers.
