Question of understanding: Bridges

Hi,

I've got a question: I understand bridges as software links of at least two interfaces belonging to different ethernet networks. Therefore a bridge connects two networks on OSI layer 2, enabling communication by intelligent packet distribution. Please correct me, if my understanding is wrong.

However, do the bridged networks have to have different IP subnets? Or since bridges are on layer 2, may the networks all be eg. in 192.168.1.1 range with DCHP Server in one network?

I really...
