Help with an network exercise

Hi, so I'm doing a course of cyber security and we are viewing some basics of networking and in one of the exercises they give me the following ip packet:

" 0100 0111 0000 0000 1111 1000 0000 0001 1001 0010 1111 0101 0011 1111 1110 1101 0000 0010 0000 0110 0101 1100 1111 0000 1100 0000 1010 1000 0000 0100 0011 1011 0000 0010 1101 0100 0000 1101 1010 0101 1111 1111 1111 0000 0000 1111 1010 1010 0111 1100 0000 1010 0010 0000 0000 1111 1000 1000 0101 1100 0000 0000 0001 0110 1010 0111 1111 0001 1110 0000 1001 1011 1111 0000 0100 0111 1011 0111 0111 1000 0110 0000 0000 0000 1111 1000 1100 1100 0111 0110 1001 0010 1000 0000 0000 0000 0100 1110 1001 0010 1000 0111 0100 0000 .... "

And I need to figure out the source ip, the destination ip, what port they're using for communicate, what protocol the communication use (TCP or UDP) and how many TTL this packet will have before it get discard.

I really got stuck and I wish I can get some help, thank you very much !
