Route53 – How to Redirect www to Non-www

amazon-route53domain-name-systemredirect

I host my site at domain.com.

My DNS entries in Route53 are as follows:

domain.com      A       xxx.xxx.xxx.xxx      300
domain.com      NS      stuff.awsdns-47.org  172800
domain.com      SOA     stuff.awsdns-47.org  900

I would like to redirect traffic from www.domain.com to domain.com, as currently this just returns a 404. This question on SO suggested a PTR record, and I added that:

www.domain.com  PTR     domain.com           300

but it didn't work. What should I be doing?

PTR is for setting up reverse IP lookups, and it's not something you should care about. Remove it.

What you need is a CNAME for www:

www.domain.com  CNAME  domain.com 300

Awesome! A good answer was given by anonymouse in a comment to the post:

Have you tried opening the site directly from the host to rule out any funky dns issues? I.E., add an entry for www.domain.com and domain.com to /etc/hosts and then open the site with links from a command prompt. If you've setup a separate virtualhost (non wordpress site) and you're still getting redirected back to domain.com then i would be suspect of Via: 1.1 ISA in the http headers. A quick search reveals Microsoft Internet Security & Acceleration Server. A reverse proxy and caching server among other things. It could be causing problems

The problem was (well, is) the ISA server. I still have no idea why this happens since I don't run that server, but adding both hosts to /etc/hosts and locally doing a wget -S on it gave me the proper behavior.

I'll need to talk to the people running that server to see if they know what it's about, but at least that explains why I couldn't get any sense out of what was happening.

Edit: Fixed! Changing the "To" rule site name in the ISA server rule fixed it, even though link translation was off.

DNS redirect error (probably CNAME related)

Without seeing the actual records, you will want to do a DIG (or NSLOOKUP) on the domain and look for what gets returned with and without the www.

This is how stackoverflow.com is set up. If you are missing either a CNAME or an A record for both the www and without, that is your issue.

stackoverflow.com.  1200    IN  A   64.34.119.12
www.stackoverflow.com.  1200    IN  CNAME   stackoverflow.com.

If you post the domain, we can better help. Also, this question should be on serverfault.com , I have requested it be moved there as it is not programming related.

EDIT: 10/10

Since you are seeing the A record, but the internet is not, it is possibly due to the domain pointing to the wrong name servers.

Name servers:
        dns1.fluent.ltd.uk        195.78.94.253
        dns2.fluent.ltd.uk        195.78.94.254

You mentioned switching web hosts, if that is not your current web host then you need to contact 1 & 1 AG and have them change the name servers over to your current web host so the internet sees the correct DNS records.
