These are only ways to get hostel if you are not from outside Delhi:

1. Give address proof of outside Delhi(works only if you are not in 1st year as from this year freshmen of only outside Delhi category are being given hostels).

2. Use any sources or contacts, if you have. It's the only way if you don't have address proof of outside Delhi and you are in 1st or 2nd year.

3. Get involved in something big like UAV etc. And have no back logs with satisfactory score , then you can go plead to hostel warden, VC or any authority that may help you in getting hostel. Show them that you really need hostel(persistence is required) and you cannot waste traveling 3-4 hrs a day, there's a fair chance you'll get hostel. (Can work for 3rd year onward and definitely not for 1st years).

The first two are not in everyone's hands and third one is not for freshmen so I'll advice to rent a room or flat nearby in that case.
