I’m not looking to make money either. Just get them distributed and I don’t have much excess cash to just give them away for free.

Let me know when the new ones are out. I may get them printed up… And possibly given away at cost.

If it is caching you can always set a ttl to a lower value like 5 seconds. And systems should be clearing the dns cache on a new ifup.

Set up an internal dns server that will resolve your specific host name to an internal ip and forward everything else.

If you just want a specific site, you can use bind and response policy zones. The advantage of this is that you can now configure your dns server to take advantage of block lists on the internet and block malware/ads/tracking domains.
