Error: dns_get_record(): Type ‘251721779’ not supported

I am trying to get the DNS records for a domain. All of the commands work to get the MX and other record types but when I try to use DNS_ALL I get the error "Error: dns_get_record(): Type '251721779' not supported".

[apcode language="php"]

$dnsres = dns_get_record  ($domain, DNS_ALL);

[/apcode]

It seems like its an issue with the DNS_ALL not equaling what it should? I don't know how to debug this better. Has anyone found a way to fix this?
