Hello fellow hosters! In response to a comment left on my most recent article (Making DNS Record Changes in cPanel), I decided to blog about how to change DNS zones in an ASP hosting environment. Specifically, using Arvixe’s WebsitePanel. This is a quick and easy procedure, but PLEASE DO YOUR HOMEWORK! Changing DNS records can cause all kinds of havoc if done improperly. I’ll repeat what was said last time:
ATTENTION: Do not attempt to modify these fields unless you are absolutely sure what you are doing! This tutorial will provide a bit of background on each type of record, but is not for beginners. Please contact Arvixe support if you are not 100% comfortable with these actions and their consequences.
The bold text means it’s serious! Okay now that the disclaimer is out of the way, let’s move forward to navigating the user interface to find the controls.
Get logged into your WebsitePanel via one of the following methods:
Once logged in, click “Domains”. Once in that screen, select the domain you wish to modify the DNS for.
From this screen, you can select the link “Edit DNS zone records”.
From within this page, you can add a new record, or modify and delete existing records:
Deleting a record is straightforward and simply erases the record.
Adding a new record brings you to this page. Note that modifying a record brings you to an identical page, but with the record type locked in place already.
What are these different record types? Here is a synopsis, that I wrote up in the last article.
A records are what translate your website’s URL into an IP address. An example of a A-record would be “www.google.com –> 188.8.131.52″. More info here.
NS records dictate the name servers to be queried. All Arvixe servers have them, generally denoted with “ns1″ and “ns2″ subdomains.
MX records point to the service that handles email traffic. They are also associated with a priority, in case there are more than one.
CNAME records translate one URL into another. For example, “ftp.domain.com –> domain.com” would be practical if your server had both FTP and HTTP functions (like your Arvixe server does). More info here.
TXT records are places to store arbitrary text information. Most commonly used to validate the source of emails and other communications, so that other senders can’t fake their email address to look like someone else. You don’t really need to be touching this, though. More info can be found here.
SPF records protect you from harmful UV rays that result from long exposures to sunlight (Just kidding). In seriousness, it is a newer and more robust form of a TXT record. Here is a good explanation via Wikipedia: If a domain publishes an SPF record, spammers and phishers are less likely to forge e-mails pretending to be from that domain, since the forged e-mails are more likely to be caught in spam filters which check the SPF record. Therefore, an SPF-protected domain is less attractive to spammers and phishers. Since an SPF-protected domain is less attractive as a spoofed address, it is less likely to be blacklisted by spam filters and so ultimately the legitimate e-mail from the domain is more likely to get through.
Have fun and happy hosting!
