About RequestBin
This website is next-generation of requestb.in which has been stopped on 2016. In this version, we have combined DNSBin and RequestBin into a single function. A subdomain is provided to you that will collect requests made to it and let you inspect them in a human-friendly way in both of DNS and HTTP protocol.
Our source code is open on Github: https://github.com/requestbin/
