Try BCDNS for yourself

User guides, documentation and web administration tools are currently under development. In the meantime, you can try BCDNS by invoking the linux 'dig' command to retrieve data from the BCDNS blockchain:

• dig @bcdns.invykta.com -p 5353 invykta.com

• dig @bcdns.invykta.com -p 5353 invykta.com MX

• dig @bcdns.invykta.com -p 5353 colostate.edu

• dig @bcdns.invykta.com -p 5353 cs.colostate.edu TXT

• dig @bcdns.invykta.com -p 5353 stephen.hayne.certs.invykta2.com TXT

The results, of course, look just like a normal dig, but the data is coming from the blockchain. This demonstrates compatibility with conventional DNS.

Now try the following queries:

• dig @bcdns.invykta.com -p 5353 google.com

• dig @bcdns.invykta.com -p 5353 twitter.uk

These will return with an error code "REFUSED". This is because there is no data for these domains in the blockchain and therefore BCDNS is not authoritative for this query. The query is refused because you are querying an authoritative server, not a caching server.

If you are using a VPN such as NordVPN, try changing your server location to Mexico, Poland or Vancouver, Canada. Then do the following dig, which should return a different TXT message depending on the query GEO-IP location:

• dig @bcdns.invykta.com -p 5353 test.invykta2.com TXT
