Disabling A records for IPv6?

[Robin Lee Powell]

Here's the digging my ISP did:

[root at dvs-node01 ~]# node
> var dns = require('dns')
undefined
> dns.resolve('github.com', function(e, h) { console.log(JSON.stringify(h)) } )
{ oncomplete: [Function: onanswer] }
> ["207.97.227.239"]
undefined
> dns.resolve6('github.com', function(e, h) { console.log(JSON.stringify(h)) } )
{ oncomplete: [Function: onanswer] }
> ["2001:db8:1:ffff::cf61:e3ef"]
undefined
> dns.resolve4 = dns.resolve6
[Function: query]
> dns.resolve('github.com', function(e, h) { console.log(JSON.stringify(h)) } )
{ oncomplete: [Function: onanswer] }
> ["2001:db8:1:ffff::cf61:e3ef"]

So it seems that node's basic DNS function *only* returns IPv4
addresses.  Or something.
