 I need your help in extracting the domain and top level domain from dns queries where:

 

Query Field                  |         extracted field

Account.fb.com         .         Fb.com

Aa.bb.cc.com              .         Cc.com

Www.google.com      .        Google.com

 

 

 

Thanks in advance
