Re: Why does checkdnsrr() default to MX??

I was just composing an e-mail advising you to follow general netiquette rules and read the original post. :) I disagree utterly that I did not sufficiently address the question. I addressed it in multiple ways: [1] ANY queries create extraneous traffic, so you want fewer PHP functions defaulting to them, not more; [2] ANY queries may fail, giving a false negative, when individual RRs would succeed; [3] An ANY query that only reduces to a *boolean *is a particular waste of energy and network traffic if you're trying to see whether a domain has any records, as you can use SOA for that, with no loss of fidelity; [4] *if* checkdnsrr() is generalized from dns_get_mx() that is another explanation I think [4] is actually my weakest point. -- S.
