This is a followup question to my previous post Multiple free dns services redundant as name servers of a website?
I would like to setup DNS services as primary/secondary, master/slave and would like to know which is the better of the two options that my Domain Registrar provides.
OPTION 1
Use the domain registrar`s free DNS servers 1 and 2 (must use as primary and secondary) as the following:
PRIMARY ns1.domainregistrarfreeservice.com
SECONDARY ns2.domainregistrarfreeservice.com
NS ns1.everydns.com
NS ns2.everydns.com
CNAME entries...
MX entries…
OPTION 2
Use the domain registrar`s name server as a secondary DNS by providing a Primary server IP address and will use ns2.domainregistrarfreeservice.com as secondary zone transfer (I am not quite sure what this is). The following entry will also be needed in the Primary server
named.conf
------------------------------------------------------------------
zone "example.com" IN {
type master;
file "example.com";
allow-transfer {
some.ip.address.here; ←ns2.domainregistrarfreeservice.com
};
};
------------------------------------------------------------------
I thought I would add and do not believe it matters, but my hosting service is not on any of these DNS hosting services.
