Hi all,
How can I achieve the below using iRules.
if clients from [network1, network2...] querying [sub.domain.com] --answer--> 1.2.3.4;

NacreousOk, let's try this one 🙂
when DNS_REQUEST {
set ttl 1800
set A "[DNS::question name]. $ttl [DNS::question class] [DNS::question type]"
if { [string tolower [DNS::question name]] ends_with "sub.domain.com" } {
DNS::answer insert "$A 1.2.3.4"
}
DNS::return
}

NimbostratusThanks Yann, is the below correct
when DNS_REQUEST {
if { [string tolower [DNS::question name]] ends_with "sub.domain.com" }
{
if { ( [IP::addr [IP::client_addr] equals 10.1.0.0/13] ) or ( [IP::addr [IP::client_addr] equals 10.2.0.0/13] ) }
{
set ttl 10800
set A "[DNS::question name]. $ttl [DNS::question class] [DNS::question type]"
DNS::answer insert "$A 10.10.10.2"
}
}
else {
return
}
DNS::return
}
