ColdFusion 9 Wish List - Domain Information Groper

May 16, 2008

So in the Linux world there is a really great tool called DiG which stands for Domain Information Groper. Basically, it helps you query up the records from a DNS server. Windows has nslookup, but DiG is far more powerful. For more information on DiG go to

It would be handy if the next release of ColdFusion had a tag that did could do the same calls as DiG and return the results into a query. So for example, you could verify an email by doing a DiG call to verify the domain exists and has valid records. Another possible application could be a situation where your mail server location changes frequently. Instead of specifying the mail server address in your code, you could do a DiG call to determine your current mail server and then use that location in your cfmail calls. The same could hold true for CFPOP uses.
