Hi currently ALL our computers which is joined to the domain configured with DNS suffix search by default
which is the domain name Mycompany.com now if i try to do nslookup for any external lookup it will try it in the following order
1- QUESTIONS:
GMAIL.COM.Mycompany.com, type = A, class = IN
2- QUESTIONS:
GMAIL.COM.Mycompany.com, type = AAA, class = IN
3- QUESTIONS:
GMAIL.COM, type = A, class = IN
as you can see in the third question it will try the correct name.
now i read in many blogs that we can solve this by changing the DNS suffix search list from the NIC configuration by adding "."
then my domain name.
but this will affect all our internal hosts because if i do nslookup for any internal host for example MyWebServer i will receive error
this record can't be found because our domain name not automatically append to the record willdoing the nslookup
so what i need is a solution to have fast name lookup resolution for theexternal record without DNS request timed out and
in same time i want if i do name lookup for any internal record it should append the domain name to the name.
