1.What is DNS?
The Domain Name System (DNS) is a networked computer system with a massive database of Internet domain names and their corresponding addresses, which is constantly kept up-to-date. It helps users to find their way around the Internet.
Every computer on the Internet has a unique address - just like a telephone number - which is a complicated string of numbers called its IP address (IP stands for Internet Protocol). IP addresses can be hard to remember. The DNS makes using the Internet easier by allowing a familiar string of letters - the domain name - to be used instead of the arcane IP address. For instance, you only need to type zname.com to reach our website, instead of the IP address 47.75.112.226.

2.How does DNS work?
When you make a network request to a domain name, your computer needs to know where on the Internet that domain is located. It gets this information from the DNS. Your computer sends a request to the DNS containing the name of the domain, and the DNS responds with that domain's numeric IP address. Your computer then proceeds to connect to that address. The process is referred to as domain name resolution: a domain name resolves to its corresponding address.
DNS allows network clients to convert Universal Resource Locator, or URL, into IP address. This is a key part of network operation, as computers and other devices generally need to know each other's IP address in order to communicate over a network.

3.How do I resolve my domains?
To resolve your domains, please follow these steps:
(1) Sign in to your Zname account.
(2) Select "Domains" from the left-side menu bar and click "Bulk Operation" in the drop-down.
(3) Choose "Bulk Name Resolution" from the "Bulk Operation" list.
(4) On the DNS Settings page, choose the "Record Type" you want to use from the drop-down menu. If you have an Email Server or MX Record available for your domain email, enter in the hostname and the distance (otherwise known as priority) in the subsequent text boxes. You can also specify subdomain A records, CNAME records, SRV records, TXT records, etc.
(5) Press the "Add Resolution Data" button to resolve your domains.
Please be aware that it might take some time for your name resolution to propagate. This is what people mean by waiting for their domain to resolve. Depending on the central registry (Verisign, etc.), they may update within 10 minutes or (very rarely) take a whole day to update.
