Domain names not resolving due to trailing `.`

# Summary

When using the API resolver, domain names need to include both the regular domain name and the same domain name, but with a trailing `.` at the end or else it will sometimes fail to resolve. I.e if the target domain is `gurkult.com`, we need both `gurkult.com` and `gurkult.com.` or else routing will fail. We must revise routing to route the request regardless of the trailing dot.
