Dihing 10.0.X.Y 255.255.252.0 10.0.0.254
Kameng 10.9.WX.Y 255.255.192.0 10.9.0.254
Kapili 10.1.X.Y 255.255.252.0 10.1.0.254
Manas 10.4.WX.Y 255.255.192.0 10.4.0.254

Umiam 10.11.WX.Y 255.255.192.0 10.11.0.254

Where W is block number : (A : 0, B : 1, C : 2 and so on)
X : Floor Number (Ground Floor : 0 / First Floor : 1 / Second Floor : 2 / Third Floor : 3)
Y : Room Number (Last or last two digits of room number) Z(Only for Brahmaputra) :

A & B block Room Number (Last or last 2 or 3 digits of the room no.)
C & D block - Ground Floor Room Number - 134(eg. 199-134 = 65)
C & D block - First Floor Room Number - 119
C & D block - Second Floor Room Number - 133
C & D block - Third Floor Room Number - 131

So someone staying in hostel Dihing, room number : 222; i.e. 2nd floor room number 22 will have an IP Address of 10.0.2.22. Similarly hostel Umiam, room number: B-103; i.e. block B, 1st floor, room number 3 will have an IP of 10.11.11.3 and so on
The Default Gateway and Subnet mask are as given in the table. The Preferred DNS Server 202.141.81.2 and alternate DNS Server 202.141.80.9 are default for everyone.
