Could DNS help solve this?

In addition to the eminently practical and useful suggestion already given (using the command line whois client that comes with most Linux, Mac, or *BSD systems), I'll point out that there are some whois servers whose presence is given by DNS records, specifically SRV records. Some random samples:
$ dig +noall +answer srv _nicname._tcp.de
_nicname._tcp.de. 86389 IN SRV 0 0 43 whois.denic.de.
$ dig +noall +answer srv _nicname._tcp.us
_nicname._tcp.us. 518400 IN SRV 0 0 43 whois.nic.us.
$ dig +noall +answer srv _nicname._tcp.mx
_nicname._tcp.mx. 172800 IN SRV 0 0 43 whois.nic.mx.
$ dig +noall +answer srv _nicname._tcp.au
_nicname._tcp.au. 259200 IN SRV 0 0 43 whois.ausregistry.com.AU.
$ dig +noall +answer srv _nicname._tcp.co.uk
_nicname._tcp.co.uk. 172800 IN SRV 0 0 43 whois.nic.uk.
