So I'm a Windows / Network admin, have been for 2 years, but today I had a question that I didn't really know the answer to.
Say I do a nslookup, and the query retrieves 2 A records.
Which A records does say, a browser use?
If we do an nslookup for google.com, we get many responses. Is there a preferred address that windows uses? Is there any deciding factors?
If you have three A records in example.com a,b,c
The first query will retrieve a.example.com
the second b.example.com
the third c.example.com, and the next will get a.example.com again.
This is known as round-robin DNS
