I used an IPv6 tool and it looks like coap.exosite.com is up and running. Looks like the problem was on my end after all, thanks for your help!

Yes, the example will query the Google IPv6 DNS server for the IPv6 address of the hostname coap.exosite.com. If you do not have IPv6 connection, it will not reach the server, and you will not get the address. You can try pinging the coap server using an online IPv6 ping tool to check if it's up and running.

Sounds like setting up an IPv6 tunnel would be my only option considering that I am attempting to send the packets through the RPi to the exosite cloud server. So, I am assuming that when the nrf52 says "DNS Response for hostname: coap.exosite.com, with 0 IPv6 addresses and status 0x0000C440" it could mean that my network doesn't support IPv6 not that the exosite server I am trying to access is faulty.

Yes, this means you don't have IPv6 connection. There is a couple of solutions to make the devices connect to internet:

Setup IPv6 tunnelling. This will allow two-way communication with the devices from IPv6 internet. You can find a blog post providing some details on one alternative provider here.
NAT64: This solution run on the RPi and will translate the IPv6 packets from the IoT device into IPv4 packets. This allows your IPv6 enabled IoT devices to talk to IPv4 internet, but not to IPv6 internet. It is also not trivial to connect to the IoT devices from IPv4 internet, as this translation is more complex.

I would suggest going for the IPv6 tunnel solution until you get native IPv6 connection. This will make the transition simpler when you get access to IPv6 network.

No IPv6 address detected [more info]

Good news! Your current configuration will continue to work as web sites enable IPv6.

You appear to be able to browse the IPv4 Internet only. You will not be able to reach IPv6-only sites.

Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access.

This is what the online test service returns. Does this mean I dont have an IPv6 connection? If so is there a way around it? Thank you so much for your help.

You can test your IPv6 capabilities from a online test service like this one, or you can try pinging an IPv6-only webpage from the Rpi:

ping6 ipv6.google.com

Im assuming so, considering that i am on a corporate network in the united states.

Do you have IPv6 connection on your local network and from your ISP?
