What DNS entries do I need to setup for test.example.com to respond to pinging?
Here's my DNS entries as I've setup through Linode:

2If you're not going to bother obfuscating your screenshots, you may as well use your domain in the question. Or at least make it clear that `example.com` is really the domain in your screenshot if you don't want your domain name indexed. – MikeyB Aug 17 '11 at 01:58

I didn't intend to. Force of habit made me generalize the question. `example.com` is the one address that I can site that won't be porn in 5 years. I can't say the same for my own domain. – Stefan Kendall Aug 17 '11 at 02:39

Is it possible that either the server is configured to not respond to pings or that there is some form of firewall preventing its response from reaching the destination? – John Gardeniers Aug 17 '11 at 04:51

The A record for test that you already have in there is the one you need.
It's working - you might not have waited long enough for the DNS.
Pinging test.wendler.mobi [97.107.134.245] with 32 bytes of data:
Reply from 97.107.134.245: bytes=32 time=75ms TTL=51

2Just to clarify - pinging is, in absolutally no way, related to DNS. It just so happens that DNS *may* form part of the `ping` command, but apart from that, they're two totally different concepts. – Mark Henderson Aug 17 '11 at 01:38

I wonder if google's DNS servers update less frequently than others. – Stefan Kendall Aug 17 '11 at 01:41

On the off chance you actually meant test.example.com literally, you would have to speak to IANA about this one. See http://www.example.com and RFC 2606 for gory details and a cure for insomnia :-)
Otherwise like Shane said, patience is a virtue when dealing with DNS (at least as patient as the negative result cache time).
