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:

If 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 1:58
    
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 2:39
    
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 4:51

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

Just 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 1:38
    
Huh. It's been over 24 hours. I guess I'll keep waiting. –  Stefan Kendall Aug 17 '11 at 1:39
    
I wonder if google's DNS servers update less frequently than others. –  Stefan Kendall Aug 17 '11 at 1:41
    
@iftrue 8.8.8.8 seems to have it... –  voretaq7 Aug 17 '11 at 1:43
    
Okay, seems to be up now. Neat. –  Stefan Kendall Aug 17 '11 at 2:40

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).
