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.
