unknown host - but it shouldn't be

[Pat Richard]

Greets!
 
I'm running rsynch 2.4.6 on a RedHat 7.x machine. I'm attempting to use
the following line:
rsync -avzC --timeout=600 --delete --delete-after \
rsync.php.net::phpweb /path/to/php folder
 
but I'm getting an 
unknown host: rsync.php.net
 
but if I ping the site, I get 
ping rsync.php.net
PING va1.php.net (198.186.203.51) from 63.163.7.66 : 56(84) bytes of
data.

rsync works fine when I attempt to sync from other sites, but I've only
been using it for a couple days. I'm assuming this isn't an rsync issue,
and thought I would ask for any advice.
 
Thanks!
