DNSNameToWebsite QueryPorts
From Paterva Wiki
DNSNameToWebsite_QueryPorts
This transform basically converts DNSName to Website. Before simply changing the types the transform will query port 80 on the DNS Name and see if it can get a proper HTTP response. Currently only port 80 is tested. In upcoming versions port 443 will also be tested. The transform also populates the server type and the HTTP ports in the additional fields.
Typical uses
This is a bridge transform.
