Multiple DNS Lookup Engine
Special feature: performs simple automatic network mapping.
http://www.bankes.com/nslookup.htm
Another invaluable web tool, the Multiple DNS Lookup Engine does something
unique, as far as I know: it steps you through an entire IP address block (up or
down). You either enter an IP address or a domain name and decide whether
you want the lookup tool to step up or down from that address. The tool then lists
the next address in the "neighborhood," associated IP or domain name, and in
some cases, links to registration information. This tool is ideal for mapping a
network.
Netcraft
Netcraft Search Help

Special features: true wildcard function against all TLDs; provides information about
what a site is running.
Netcraft is many researchers' favorite lookup tool because of its flexibility and
power. Netcraft is designed to perform wildcard searches of domain names and it
queries all TLD extensions. The simple search offers the option of searching for a
domain name where the search string contains/starts with/ends with or matches
a subdomain.l'" Netcraft also offers three wildcard options: * matches any
number of characters; ? matches a single character; [ ] matches on specified
characters. A search for [*.sc[aeio].com ] returns all domains that contain
sea. com, see.eom, sci.com, or sea. com. A search for sites that contain ".ir"
returns sites such as www.irs.gov.whereasasearchfor[*.ir] finds only those
sites in the Iranian domain. If you search for [*.gov.ir] Netcraft returns 11 sites,
including ..www.mfa.gov.ir.. and ..intranet.mim.gov.ir." What's more, for each hit,
you have the option of seeing "what's that site running," which, provides
information about the operating system and web server at the site.
Whois.net
http://www.whois.netl
Special feature: wildcard matches search string anywhere in domain name, or
string anchored right or left.
Now that Whois.net searches most TLDs, it is one of the very best lookup tools
on the web. As with Domainsurfer, the Whois.net keyword search will find
smithsonian as well as sonia-net in its default mode. In order to find domain
names that begin or end with a string, use the advanced search form, which is
accessible from the search results' page. ,
153 As of this writing, the "site starts with" and "site ends with" options are all resolving to "site
contains."
