I will be greatful if anyone helps me.

    Thank you

  • If you need to ask, you shouldn't be doing it.

    But if you must:

    Create a DNS server with the zone and records you require to be available to the internet, this will need either an External IP address or a NAT'ed IP address accessable from the internet.

    Make sure the firewall has port 52 open to you new DNS server

    Have your Domain name registrar enter the host name and IP address of your new DNS server as the authoritative DNS server(s) for your domain.

    Actually, just thought I would mention, it's TCP 53 and UDP 53. You may have to check the firewall docs to insure it will allow EDNS0 (UDP traffic sbovr 512 bytes), too.

    Some points to add:

    • The Registrars require a minimum of 2 Hostname Servers (DNS servers) per zone.
    • Therefore, two separate servers, or two virtual servers, are required.
    • It's required to have a business class ISP line to allow inbound requests. Check with your ISP for more info.
    • It's required to have two external static IPs for the two servers. Check with your ISP for more info.
    • It's recommended to have 24/7 electrical backup power.
