DNS zone validation warnings

I just used “http://www.intodns.com/” to test my DNS setting. What is this below problem? How to solve it? Different autonomous systems WARNING: Single point of failure and Different subnets WARNING: Not all of your nameservers are in different subnets The subnet error just means you’re putting all your eggs in one basket! There’s an RFC, if my memory serves, that asks for two different physical locations (or at least subnets) for the Name Servers under […]

Very slow DNS I think

looking for advice on my new VPS I have set up with help from a friend. Everything seems to be working well and pages load quickly after the first page load, the first page load takes up to ten seconds even for simple text based websites.

DNS, Do A Record wildcards have priority over more-specific CNAMEs?

We have a wildcard set up to handle all subdomains for “example.com” A RECORD: *.example.com points to 10.10.10.10 We have a more specific A record to handle a special subdomain (this works fine): A Record: staging.example.com points 10.10.10.9 The problem we’re having is we’re migrating staging to a new hosting environment and we’ve been instructed to use a CNAME: CNAME: new-staging.example.com points to proxy.heroku.com We thought this would work. However, new-staging.example.com resolves to the top-level […]

Problems adding new domain to httpd.conf file

So, I just bought a brand new domain. I set up my dns records with the host (godaddy) but something strange happens on my server. I’ve added this to the httpd.conf file: <VirtualHost *:80> ServerName www.newdomainname.tld DocumentRoot /usr/share/roundcube/ </VirtualHost> But somehow I’m redirected to the root of my server. Then I tried adding this under the entry for the new domain name: <VirtualHost *:80> ServerName shop.olddomainname.tld DocumentRoot /usr/share/roundcube/ </VirtualHost> And it worked without any problems.
