NSONE - creating geo resolution records

Configuring a geo resolution record in NSONE involves

• Start editing a record.
• Create multiple regions and assign geographies to the regions. 
• Create multiple answers and assign a region for each answer. 
• Create a filter chain and use the GEOTARGET_COUNTRY and SELECT_FIRST_N rules. For CNAME records N=1. 

See this article for in-depth instructions on the filter chain and to see how to load balance multiple answers within a region.
