Hello All,

I have a question related to CNAMEs, A Records and DNS.

It is not really a direct DNN question, so close that some of you must have had the same issue, please forgive me if it is OT

I have a DNN site that hosts 20 sites / portals.
Customers site is www.example.com
Customer currently points his A record to my IP address
Customer points his CNAME to his domain
(This is the usual configuration for most domains)

My site is www.hostingsite.com

My problem is if I change IP address, I have to ask 20 customers to update their DNS details.  Not Easy!

I have created a CNAME on my site named portals.hostingsite.com
I will ask all customers to change their CNAME To point instead to portals.hostingsite.com

This means that www.example.com will be re-directed to portals.hostingsite.com.  My server will then serve the site.

This all works well today, got CNAMES.

However...

The A record is not so easy. You cannot point an A record to a CNAME.  It must point to an IP address.

The reason I am posting all this here is to ask you what you think about this topic.

There is a company http://wwwizer.com/naked-domain-redirect that offer A record re-direction for free.  Do you think there is anything wrong with re-directing A records via a company I am not familiar with ?

thanks as always for your advice

Mark

CName and A records in DNS do the same thing just by different means.

You can use 2 CName records to direct a user to the 'mysite.com' and 'www.mysite.com' addresses to portals.hostingsite.com. Just as you can use 2 A records to direct the addresses to a single IP address.

A forwarding service will still need the record for an address in the DNS. If the forwarding services IP address changes you are in the same position as when your own IP changes. Also, you have to take into account how the service does the forwarding and the impact the method has on the sites search engine visibility.

So if you don't want your clients to change DNS records when you change your IP address then they should use CName records for all the addresses used by the websites.

Bear in mind that CName records increase the number of DNS lookups because the alias also has to be resolved. This does add some time to the page loading process, though usually only milliseconds.
