I used to use linode and this is what I had in db file:
ttl 86400 example.com. IN SOA li153-35.members.linode.com. foo.example.com. ( 2011051301 21600 3600 604800 86400 ) example.com. IN NS li153-35.members.linode.com. example.com. IN NS ns1.linode.com. example.com. IN A 184.108.40.206 www IN A 220.127.116.11 * IN A 18.104.22.168
Then on my domain registrar I modified the dns of my domain with the linode ones. I have no idea what to use for my primary and secondary dns on ec2, doesn't ec2 has dns like linode used to offer? What should I do?
