problem with Resolv.rb

There's an unreasonable limit in resolv.rb:

at about line 1338:

class NS < DomainName
TypeValue = 2
end

which means you can only get the first to name servers back. Can this
be overridden at runtime (it complains about it being an already
initialized constant when I try)? If it can not be overridden, would
it be reasonable to bump this up to some other number (10 or so) in
the distributed version of resolv.rb?

thanks,

This corresponds to RFC 1035:

| TYPE value and meaning
|
| A 1 a host address
|
| NS 2 an authoritative name server
| ...

Tanaka,
thanks for the reply. It looks like we misunderstood something then
when we were troubleshooting our problem. Only 2 NS records are
returned in our test (dig returns all 4), The only place we saw what
looked like a limit was the TypeValue. Is the limit being enforced
somewhere else?

I'm away from the office right now, so I don't have access to the
code, but I can share it tomorrow.
