Description Stephen Allen 2008-12-05 01:50:00 UTC 
In the section "Access Control Commands --> restrict", it says:

"The address argument expressed in dotted-quad form is the address of a host or network.  Alternatively, the address argument can be a valid host DNS name."

I have found that the address argument MUST be an ip address only - it doesn't work with a valid host DNS name.  This corroborated by the official documentation at: http://support.ntp.org/bin/view/Support/AccessRestrictions#Section_6.5.1.2.1. which says:

"You must use an IP address on the restrict line."

Fix: 

n/a
How-To-Repeat: In the restrict line, use host DNS name instead of IP address.

Please find attached a patch to remove hostname reference from the 
restrictions ACL.
