DNS types

[tuxthemadpenguin]

I'm a big fan of this app after going through many, many apps looking for some good output.  I really just wanted the power of dig on my iPhone.

I do keep other DNS apps on the phone because the DNS types I can search for is oddly limited(no CNAME?).   Can we have a write in/other type?  If not can you add axfr,cname, and caa?

Actually, any DNS lookup software should also accept numeric types so that new entries can be looked up prior to full support for them.

Wouldn't work.  The necessary part is decoding the reply.  An unknown type could only be reported as hex bytes or just "undecodable".  This is the same reason unknown types can't even be forwarded by caching server or slave server.  I suspect this is why many new things are encoded in TXT fields.

Of course, a DNS lookup software should support "ANY".  (Maybe I should make a DNS server that returns weird or random data, just to see what the clients make of it. ;))

But with numeric input, at least you get an output.....

The output could only be "Unknown record of type n with undecodable content".  The content bytes could be output, but domain names would often be undecipherable due to trailing domain compression.  OK, there might be some value to showing the unknown records. 

Note that you really are better off with an ANY query to fetch this.  (Frankly, if you are trying to browse DNS, I would always recommend "ANY", except if you are trying to deal with a partially expired cache.)
