I run my own HTTP and SMTP servers. I tried to run also my own DNS server, but somehow it failed. Either I misconfigured it or simpy didn't wait long enough for a DNS propagation (I waited about 24 hrs. and didn't see any effect). Then I found out that my domain name's registrar (GoDaddy) provides for FREE a basic DNS service and I use their generic domaincontrol DNS servers for my site. Now my quesions:
1) Why GoDaddy does it for free? Is it a regular practice for registrars to also provide a free DNS service?
2) Should I bother learn more about BIND9 and finally get it to work or it's not worth the effort and time?
3) Why when I was hosting my website with 3rd party hosting provider (Rochen) and was using their DNS servers, it took about 24 hrs. for a DNS propagation and now with a free registrar's DNS service it takes minutes to make it run?
