DNS resolution failing even with 8.8.8.8 DNS server

One of my work computers that is available via AWS fails to resolve via DNS. While on other WIFI connections, or if I use a website to resolve this site, everything works fine. However, every computer I have at home fails to resolve it on the command line. I have tried even connecting a Mac Mini via hard-wired ethernet directly to the comcast modem and turned off WIFI, and flushed its DNS cache and still it won't resolve.

It seems that Comcast is somehow poisoning the ARP resolution even on public / Google DNS servers. 

nslookup nexus3.dev.nextworld.net 8.8.8.8

When I run this in my office, via a 3rd party VPN (not one provided by my work), it resolves, but while connected to Comcast I simply get:

Server:		8.8.8.8Address:	8.8.8.8#53Non-authoritative answer:*** Can't find nexus3.dev.nextworld.net: No answer

As seen here: https://www.nslookup.io/domains/nexus3.dev.nextworld.net/dns-records/

The server is publicly resolvable. I can't understand why it will not resolve while on the Comcast internet.

As a work-around, I have to hard-code the IP address in my `/etc/hosts` file, but this is not a good solution as the IP address does change fairly regularly. 

Any idea on how to get Comcast to not block / affect DNS resolution for this site?
