For Geolocation Routing Policy, What happens if the user tries to access from the region/location which is not registered
2 Answers
I found this on AWS doc:
"Geolocation works by mapping IP addresses to locations. However, some IP addresses aren’t mapped to geographic locations, so even if you create geolocation records that cover all seven continents, Amazon Route 53 will receive some DNS queries from locations that it can’t identify. You can create a default record that handles both queries from IP addresses that aren’t mapped to any location and queries that come from locations that you haven’t created geolocation records for. If you don’t create a default record, Route 53 returns a "no answer" response for queries from those locations."
https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html#routing-policy-geo
R53 checks for 1.State 2.Country 3.Continent 4.Default (optional) It returns the most specific record or "NO Answer". Geolocation routing only returns relevant locations.
