Re: PING and DNS resolution Acting Odd

On v7.2...

ping api.sandbox.paypal.com
Verifying connection to host system API.SANDBOX.PAYPAL.COM at address
173.0.82.78.

ping 'api.sandbox.paypal.com'
Verifying connection to host system api.sandbox.paypal.com at address
173.0.82.78.

might take a look at the dnsCache options of IPCONFIG

I have a client who's working with the paypal addon I created and
having some very odd results with host name resolution.

Basically on his machine it throws "Error retrieving address by name"
for api.sandbox.paypal.com.

So we tried ping.

PING 'api.sandbox.paypal.com'
returns:
Unknown host, api.sandbox.paypal.com

But, if you leave the quotes off:

PING api.sandbox.paypal.com

It resolves to the IP just fine.

Adding a host table entry for the host name also fixes the first issue
with the quotes (but I told him do NOT enter host table entries in
production for sites).

PINGing other hosts such as google, yahoo, etc with or without quotes
works just fine.

I am leaning towards a DNS issue, but I for the life of me can't think
of why it would work without quotes on the PING, but not with quotes
around the host name.
