It isn't defined - it is ENTIRELY down to the network admin.

However, it is common for consumer grade equipment to default to 
using 192.168.1.1 as the gateway address - and many admins use .1 as 
the gateway. This is NOT universal (one of the guys at work always 
uses .254 on customer networks), and it is NOT a defined standard.

I am not aware of any client that automatically configured it's 
gateway like this in the absense of other config.
