As OP has said he has a connecting domestic flight so am assuming he has valid documents to enter India.
You can stay at eaton transit hotel within the airport, else there are loads of hotel near the delhi aerocity, about 5 minutes drive. I have stayed at the lemon tree and enjoyed my stay. Heard good things about the red fox hotel also.
