In the following <code>httpd.conf</code> file, configure the <code>ServerName</code> properly.

Like below:

I would imagine that the caching DNS servers you're using aren't behaving properly (or the DNS server for the domain you're resolving isn't working properly). You can try to fix the former possibility.

Do you have at least 2 name servers registered on your network adapter? You could always swap your computer over to use a different caching DNS server to rule this out. Try Google's:

<pre><code>8.8.8.8
8.8.4.4

If you can discount transient outages on the remote server you are trying to connect to, then that just leaves the local network config as a problem. 

Using the IP address instead of the hostname is only going to work for the default domain on the remote host.

What happens when you try using www.google.com (or its IP address)? If you stil can't connect, then its something to do with the network between your server and the outside world.

Although this is a old thread, I have come across the same error recently while running nslookup in CentOS 7 and google search led me to some of the discussions in SO including this one. However, adding the nameservers entries to /etc/resolv.conf alone did not help as the nameserver values in resolv.conf were overwritten by the NetworkManager with the default DNS nameservers that are in the eth profile associated to the ethernet IP config.

As mentioned by @m-canvar, set the following entries in /etc/resolv.conf

<pre><code>search yourdomain.com
nameserver 8.8.8.8
nameserver 4.2.2.1
nameserver 8.8.4.4
</code></pre>

To prevent overwriting these entries by NetworkManager, there are two two approaches:

Option 1: Either set NM_CONTROLLED=no in the eth profile associated to the IPv4/IPv6 profile.

Option 2: Disable NetworkManager service from running.

<pre><code>chkconfig NetworkManager off
service NetworkManager stop
</code></pre>

Although I didn't use this exact function I got this same error.

In my case I just had to remove the protocol.

Instead of <code>$uri = "http://api.hostip.info/?ip=$ip&amp;position=true";</code>

Use <code>$uri = "api.hostip.info/?ip=$ip&amp;position=true";</code>

And it worked fine afterwards
