There's a domain I want to register that requires me to enter DNS server information, specifically the DNS name and IP. Is there anyone here who can help me with this? I've never messed with DNS before.
Your host provider should supply you with the DNS information. Then you go to your domain registrar (e.g. GoDaddy.com) and enter this info where applicable. For example in GoDaddy.com after you log in, you just need to select your domain and press the "Set Nameservers" button. Then, on the right you'll have an option to enter custom name servers - you enter them, press Save changes and you're done.
The Internet requires every domain to have at least 2 servers, called primary and secondary. The secondary server will kick in when the primary server fail. When one buy/register a domain, the registrar (seller) will give temporary servers. Some will give one-page site usually giving a notice that your site is under construction and some ads/banners of their business . The rest won't. Once you register for a free or paid hosting you would be given the names and addresses of the servers which you have to give to the registrar (seller) of your domain. After a period of about 24 hours, you would have a presence in Cyberspace.
Can be 24 hours, can be almost instantly (Most GoDaddy and eNom names resolve almost instantly for me). What domain registrar REQUIRES dns info? Almost unheard of... In fact, most would rather you stick with their default, as it provides them with free advertising revenue.
