DNS Service Frequently Asked Questions
What is DNS?
Where can I learn more about DNS?
A Name Server is a program that listens for and answers requests for DNS information. Both are terms for the file on a name server that lists a domain name with all of its associated resource records, IP addresses, and mail server information. Parts of the zone file include CNAME, and MX records. A Resource Record is an entry within the DNS system that defines an Internet resource. A resource record generally includes a domain name, its type, and a value. What functionality do DNS Tools provide? If you have an ISP that will serve your domain, you can assign "A" records so that visitors to your web site will connect to the web server that your ISP has assigned to you. You can also assign MX records so people who send you email will connect to your ISP's mail server. If you are not using an ISP for your domain name, you can tell our servers to park your domain name on the web with a "Coming Soon" or "For Sale" parking page. Also, you can redirect visitors at your domain's web page to any other web page of your choosing, using web forwarding. Additionally you can create mail forwarding that will allow you to receive any email directed at your domain name in the mailbox at your ISP or any free mailbox. What is a wildcard and does the Managed DNS Service system handle them? Address (and Mail Exchanger (MX) records support wild card entries as follows: To set up your domain so that mail for host.domain.com gets delivered to your mail exchanger, enter "*.domain.com" as an MX record. To set up your domain so that address lookups for host.domain.com resolve to a specific server, enter "*.domain.com" as an "A" record. How do I set up third-level domain names for my domain? Generally, the setup is the same as any regular second-level domain. In some cases, however, you may want to set up each third-level domain as a separate zone apart from your second-level domain. This will allow you to manage each one individually, as well as assign privilege levels to each third-level domain. An "A" record, also called an address record, ties a domain name to an IP address. If there is a server on the Internet that is configured to handle traffic for this domain, you can enter the name of the domain (like www.BulkRegister.com) and the IP address of the server (like 209.81.71.236), and almost immediately, anyone surfing to that domain name connects to the correct server. MX (Mail eXchanger) records are used to specify what server on the Internet is running email software that is configured to handle email for your domain name. If you want your ISP to handle email routing for your domain name to you, you need to specify the domain name or IP address of your ISP's mail server. In addition, you can specify the rank of each mail server when you have more than one. Make sure your ISP knows that you are using their servers to route your domain names email, or all of your email will respond with "return to sender". If you want to use our servers instead of your ISP's, do not specify any "MX" records, just configure our simple mail forwarding service. CNAME records, short for Canonical Name, create an alias from a domain name to another. You could create an alias from BulkRegister.mydomain.com to www.BulkRegister.com, and every reference to BulkRegister.mydomain.com would go to the specified location, regardless of how BulkRegister.com changed their IP addresses. However, CNAMEs will not work everywhere. If you create an MX record and the name used for the mail server was defined using a CNAME, you might lose email. Web forwarding creates a hidden "A" record pointing to our web server. When our web server gets a request for your site from a visitor, our web server is designed to forward the visitor to the URL of your choice. Mail forwarding creates a hidden MX record pointing to our email server. When we receive an email on your behalf, our email server is designed to forward the email to the address of your choice. Expert tip: If you use * for the new email address (or just leave it blank), then all email going to your domain name will be sent to the destination address, as long as it does not match another email address you have specified. Also, specifying the same new email address twice with different destinations will cause a copy of the email to be sent to both destinations. How do I create default mail forwarding for my domain name? If you use * for the new email address (or just leave it blank), then all email going to your domain name will be sent to the destination address, as long as it does not match another email address you have already specified. How do I use mail forwarding for the same mailbox to multiple recipients? Specifying the same email address twice with different destinations will cause a copy of the email to be sent to both destinations. Does registernameshere.com support round-robin DNS? Yes we do. Simply create two "A" records with the same domain name and different IP addresses, and your visitors will be load balanced between the two servers. Why can I NOT have the same domain name in multiple record types? Web forwarding requires a special "A" record to function correctly. Also, CNAMEs are mutually exclusive of "A" records, since a domain name cannot be both an IP address AND an alias simultaneously. Why can I NOT delete the "A" record for the root name of my domain name? All domains must have an "A" record for the root of the domain name. Omitting this "A" record may prevent some mail servers from delivering your email correctly. Web parking or web forwarding the root of your domain name is sufficient because both of these actions create hidden "A" records pointing to our servers. If you need to delete this record, try changing the IP address to "0.0.0.0" instead; it is functionally equivalent. How many records can I create for my domain name? As many records as you would like. Does DNS Service include Web hosting? No. DNS Service currently has no Web hosting services and no plans to implement them. However, our DNS Service package does allow you to host your domain virtually anywhere and to "tell the Internet" where to find your domain. How much are your services?
Are there any limits to what you provide? There is a bandwidth limitation per domain per year of 200 megabytes of total data transferred through our servers, for the DNSPlus package (one UNIT). Likewise a bandwidth limitation of 100MB exists for BasicDNS packages (one UNIT). Usage that counts towards your quota includes bytes transferred during DNS queries, delivery of parked home pages, delivery of URL forwarding information, and delivery of forwarded emails. If you do not use web parking, web forwarding and mail forwarding, then only DNS queries will count towards your total usage. If a single domain, with DNSPlus uses more than 200 MB of transfer space during a year, then it is considered TWO DNS units. If it exceeds over 400MB, it then counts as three DNS units. Usually DNS hits are cached, so even the busiest sites won't exceed the 200 MB limit. Approximately 200 MB should get you about 1,000,000 DNS queries. An average site uses 5 MB per year of DNS bandwidth. To register for our DNS Service, click here. |
