it is very clear if I could see
ip domain-lookup and no ip domain-lookup on the config file,

However if I couldn't see the ip domain-lookup on the config file, what is the default config? is that on or off?

ip domain-lookup is the default.  normally, unless you have a dns server configured to be looked at, you'd want to set it to no ip domain-lookup so if you screw up you're not waiting an eternity for the dns resolution to time out.
