DNS Resource Record Configuration: What You Need to Know
Posted by Jamison on 16 12 2015.
If you are looking for information on how to configure DNS Resource Records, you have come to the right place. Here, you will find a guide on the steps you need to take to perform this task and ensure that you do it right.
Must-Dos before Configuration
Prior to making any changes on DNS Resource Records, you first have to log in to the control panel of your domain name host. After which, look for the “manage” option for DNS records. Once you are in cPanel, search the “Domains” tab for the “Advanced DNS Zone Editor” option and select it. You can begin configuration as soon as you are on the page for managing the DNS records.
To Configure the A/AAAA Records
There are several fields you need to enter details in, including the following:
- This is reserved for the specific domain name you want to configure an A record for. You can also configure the record for several sub-domains. You also have the option to set a wildcard domain, however, you should know that the latter is not really considered a good practice.
- Here, you will put in a number that will indicate the length of time (in seconds) for the caching of DNS query results by other DNS servers.
- Type. This one is a drop down menu with a list of record types. Just choose the one applicable in your case. In most cases, particularly in cPanel, the default is already set to “A” record. So if it is “AAAA” you need, just click on the menu and select this option.
- Address. Just type in the server’s IP address that your domain will be pointed to.
To Configure CNAME Records
For configuring CNAME Records, the following information should be entered:
- Name. The alias you wish to set up is entered here. This should be a subdomain, since CNAME records usually do not perform well with other records. Set this one up for a root domain, and you can expect it to have problems with the SOA record.
- TTL. Again, just put a number in this field for the length of time (in seconds) you want the DNS servers to cache the DNS query results.
- Type: Choose the option for CNAME within the drop down menu.
- CNAME: Put in the CNAME record’s destination here.
To Configure TXT Records
For configuration of TXT records, the following details are necessary:
- Just put in the sub-domain for the TXT record.
- TTL. This is the same as for the A/AAAA and CNAME records.
- Type: Click the drop down menu and choose the option for “TXT”.
- TXT Data: The domain’s TXT data should be entered in this field. You can put up to 255 characters for this. It is also worthy to note that, in most cases, TXT Data needs to be in quotes (they have to be inside quotation marks). However, thanks to the convenience of using cPanel, these marks are already included, so there is no need for you to add them.
