What is a domain name?
A domain name is essentially a signpost on the Internet. Every website you've ever been to, and every email you've ever composed, has used a domain name in its address. Once a domain name is registered to a person or company, it is that person's to use exclusively as long as they continue to pay the yearly renewal fee. Our domain name is udomain.com, and we also own udomain.com.hk.


Who is involved in getting my domain name?
Once you've applied for the name, UDomain.COM accepts payment, processes the order with the corresponding registrar, and then the domain name is registered to you. This process can generally be completed within one business day. For some country specific domain names, the domain will not be ready until all documents required are submitted and verified. It takes around two business days.


What's the difference between .com, .net, .org domain names?
Originally, the three letter extensions after the dot (or Top Level Domain/TLD) were meant to denote whether the domain name was being used for business (.com) charity/non-profit (.org) or for a technology based company (.net). However, with the explosion of the Internet (and specifically, the world wide web) as a new business medium, the lines were blurred, and companies and individuals alike started cross-registering domains (ie. Me.com, me.net, me.org) just to protect their interests. Now, .com, .net, and .org names (the generic Top Level Domains) can be used for any purpose.


What's a .biz domain name?
As same as .com, .net or .org, .biz is one of the generic top-level domains. It is intended for registration of domains to be used by businesses. The name is a phonetic spelling of the first syllable of business. The biz TLD was created to relieve some of the demand for domain names in the com top-level domain, and to provide an alternative for businesses whose preferred domain name in com had already been registered by another party.


I just registered a new domain name. How soon can use it?
New domains and changes to domains may take up to 12 hours for .COM, .NET, and .ORG domains and about 24-48 hours for all other domain extensions to become effective. This is due to the number of networks involved, and the fact that those networks are controlled by several different agencies. This delay applies to all domains and all Registrars. Please allow for this delay when planning Web sites or configuring a domain to work with your email. For some country specific domain names, the domain will not be ready until all documents required are submitted and verified.


How do I pay for a domain name?
UDomain.COM accepts VISA, Mastercard via our trusted secure payment gateway. We also welcome payments by PayPal as well as company cheques and direct deposit into our bank account. If you have chosen to pay by cheque or bank deposit, you will receive our email invoice immediately after the registration. Please settle the payment as soon as possible. We can only process your domain names after receiving your payment. If you have any questions regarding the payment method, please contact us at billing@udomain.com.
