Pointing DNS to IP with WordPress on AWS

I apologize if I am asking a dumb question but I am fairly new to both WordPress and AWS.

I am running WordPress on an AWS EC2 Linux instance, and I have just changed my Host Records on Namecheap to point to the elastic IP. However, I just tested it out and when I go to my_name.com, it works properly. But when I click a new page within my website (for example: my_name.com/about-me), it goes back to the elastic IP address (i.e. 70.50.70.100/about-me). Am I missing a step somewhere? I have been googling like a mad-man but to no avail.

Any help is greatly appreciated! Thanks!
