+### Configurable record not found behaviour
+
+Added configurable strategy for record not found case. By default it won't raise an exception when DNS record not found in mocked records dictionary:
+
+```ruby
+DnsMock.start_server(port: 5300)
+```
+
+```bash
+dig @localhost -p 5300 A example.com
+```
+
+```
+; <<>> DiG 9.10.6 <<>> @localhost -p 5300 A example.com
+;; Got answer:
+;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 38632

+
+If you want raise an exception when record not found, just start `DnsMock` with `exception_if_not_found: true` option:
+
+```ruby
+DnsMock.start_server(exception_if_not_found: true)
+```
