DNS query tool

In Linux/Unix distributions, there are 3 DNS query tools provided, namely nslookup, dig and host. Only the nslookup tool is available in Windows XP. I have got the Windows version of dig and host offered by http://pigtail.net/LRP/dig/. Surprise, there is also a copy of whois ported from Linux/Unix. With all these 4 tools, I can use my Windows machine as a Linux box for DNS and whois query tasks.
