This project has been discontinued because Heroku no longer offers free plan.

`gra` stands for “Get Remote Address”. The motivation of this project was to get the remote address of a DNS that is generated with Elastic Load Balancing (ELB) from Amazon Web Services (AWS), such as More information about Elastic Load Balancing can be seen here:

It can be used to get the remote address of other DNS as well. For example, Google’s:

Terminal window
$ curl --request POST \
--url \
--header 'Content-Type: application/json' \
--data '{
"url": ""

This project was made using Express and deployed in Heroku. Underneath, it uses the built-in `dns` package which is used to resolve the remote address.
