In most cases a DNS request is sent, to ask for the IP  address associated with a domain name. An attempt to reach a domain is actually a DNS client  querying the DNS servers to get the IP address, related to that domain.

Within the Flags detail is a flag titled recursion desired. This flag shows whether or not the local DNS should continue to query other DNSs if it is not able to resolve the current query. As DNS is local, it may or may not have the enough information to allow the address to be resolved. If the recursion flag is set, the local DNS will continue to query higher level DNSs until it is able to resolve the address.  In short, the condition is when a flag is raised and it doesn’t have enough information to allow the request.
