[dnsdist] forwarding domains to special servers

[Thomas Mieslinger]

Hi,

I'm completely new to dnsdist. I'd like to use it for DNS split horizon
setup.

Goal: send queries which end with 'internal.domain' to Pool "int".

According to the documentation there are two ways to do so:

-- setup default pool
newServer({address="2001:8d8:fe:53:72ec::1"})
-- internal nameserver
newServer({address="fd7c:b55:e086:41:500c::1", pool="int"})

Possibility 1:

addAction({'internal.domain'}, PoolAction("int"))

Possibility 2:

InternalDomains = newSuffixMatchNode();
InternalDomains:add(newDNSName("internal.domain"));
addAction(SuffixMatchNodeRule(InternalDomains), PoolAction("int"));

Are there rules of thumb which possibility to prefer?

Tia

Thomas
