When using web hosting/server to host your website(get your website accessible on the internet), you might occasionally need to change your domain's DNS settings. Here are some common terms you might encounter.
[See also Domain Name Basics]
***************Attention***************
The following DNS records will be auto-generated/synchronized by NiceNIC.NET's powerful backend system for your domain name(s) registered with NiceNIC.NET if you purchase Web Hosting(get Email Hosting for FREE) at http://nicenic.net/hosting/shared.php OR separate Email Hosting at http://nicenic.net/email/ and use NiceNIC.NET's default nameservers.

1. DNS
DNS stands for Domain Name System. This system is essentially the phone book of the Web that organizes and identifies domains. While a phone book translates a name like "Acme Pizza" into the correct phone number to call, the DNS translates a web address like "www.nicenic.net" into the physical IP address of the computer hosting that site (in this case, the NiceNIC.NET's Shared Hosting or Dedicated Server services).
* To configure DNS Records with NiceNIC.NET, please follow the steps. It's FREE:
My Account > My Domain > Manage > DNS Records > Update or Add Subdomain > Restart NDNS
(1) A Record
An A or Address record (also known as a host record) links a domain to the physical IP address of a computer hosting that domain's services. With NiceNIC.NET's shared hosting services, you can add an A record to enable your "naked" domain address.
(2) CNAME Record
A CNAME or Canonical Name record links an alias name to another true or canonical domain name. For instance, www.nicenic.net link to nicenic.net. With NiceNIC.NET's web hosting services, you use CNAME records to customize the address of a web site hosted with NiceNIC.NET's shared Hosting.
(3) URL Forwarding/Redirection
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that already has been redirected, a page with a different URL is opened. For example, www.nicenic.net is redirected to nicenic.net. Similarly, Domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as when IISP.HK is automatically redirected to NiceNIC.NET. URL redirection can be used for URL shortening, to prevent broken links when web pages are moved, to allow multiple domain names belonging to the same owner to refer to a single web site, to guide navigation into and out of a website, for privacy protection, and for less innocuous purposes such as phishing attacks.
* We offer the service of URL Forwarding/Redirection for FREE for all domain names registered with NiceNIC.NET.
To URL Forward/Redirect one domain name to one existing website, please follow the steps:
NiceNIC.NET Homepage > My Account > My Domain > Manage > DNS Records > Url redirect > Update > Restart NDNS
(4) MX Record
Mail Exchange (MX) records direct a domain's email to the servers hosting the domain's user accounts. To set up Email accounts by NiceNIC.NET's Email Hosting service, you need to point your MX records to NiceNIC mail servers. Multiple MX records can be defined for a domain, each with a different priority. If mail can't be delivered using the highest priority record, the second priority record is used, and so on.
(5) TXT Record
A TXT record is a DNS record that provides text information to sources outside your domain, that can be used for a number of arbitrary purposes. The record's value can be either human- or machine-readable text. With NiceNIC.NET's domain resolution services, TXT records are used to verify domain ownership and to implement email security measures such as SPF, DKIM, and DMARC.
(6) Time To Live (TTL)
The TTL is a value in a DNS record that determines the number of seconds before subsequent changes to the record go into effect. Each of your domain's DNS records, such as an MX record, CNAME record, and so on, has a TTL value. A record's current TTL determines how long it will take any change you make now to go into effect. Changes to a record that has a TTL of 86400 seconds, for example, will take up to 24 hours to go into effect.
Note that changing a record's TTL affects how long it will take any subsequent change to happen. We recommend setting a TTL value of 3600, which tells servers across the Internet to check every hour for updates to the record. This means that next time you update the record, your change will take up to one hour to go into effect. To make subsequent changes happen even more quickly—for example, if you think you might want to quickly revert a change—you can set a shorter TTL, such as 300 seconds (5 minutes).
2. NS/Name Server Record
Name server (NS) records determine which servers will communicate DNS information for a domain. Generally, you have primary and secondary name server records for your domain.
* Register domain name(s) with ICANN & CNNIC & HKIRC Accredited Registrar - NiceNIC.NET, you will have Nameservers for FREE and you can register customized nameservers for FREE.
3. Uniform Resource Locator (URL)
A URL is the web address of a resource on the Internet. This is the address you type in a browser to visit a particular web site. For example, the URL of NiceNIC.NET's Reseller Application is http://nicenic.net/reseller/.
