Types of Queries

Information for Beginners

 

It's important to understand the difference between IP addresses, hostnames, and domains. An IP address is a unique number that identifies a computer on the Internet, for example 205.181.112.65. You may want to obtain information about an IP address to find out who is the real sender of an e-mail message, or who is attacking your computer.

 

A hostname is just an easy-to-remember name corresponding to an IP address. For example, www.tamos.com is the name for the IP address 209.68.11.237. A whois query for www.tamos.com and 209.68.11.237  returns exactly the same information.

 

Please note that multiple IP addresses may be assigned to a hostname: for instance, yahoo.com has 2 different IP addresses (206.190.60.37 and 68.180.206.184 respectively). If you would like SmartWhois to query all IP Addresses assigned to a hostname, enable the Query all IP addresses assigned to hostname option (Settings => Options => Network => Advanced).

 

Domains are different from hostnames and IP addresses. A domain is a network name registered to someone. Domain queries provide information about the owner of a domain name. For example, if you want to purchase the cats.com domain name to make a web site about cats, you may want to contact the current owner of this domain to discuss the deal. To obtain the information about the domain name owner you need make a domain query.

 

SmartWhois is capable of performing both IP address/hostname and domain name queries.

 

 

IP Address / Hostname Queries

 

To obtain information about an IP address or a hostname, just enter it in the input box and hit the Enter key (in which case the application will attempt to guess whether you entered an IP address / hostname or domain), or click on the Query arrow button and select As IP address / Hostname. You can choose a recently queried IP address or host name from the drop-down list. The examples of IP addresses are 204.71.203.160, 216.115.104.67, 195.14.130.100 (IPv4 addresses) or 2001:a00e:0000:0260:97ff:fe40::efab (IPv6 address). The examples of hostnames are quote.yahoo.com, adsl-235-235-239.mco.bellsouth.net, or www.ebay.com. SmartWhois also supports IP addresses with wildcards, such as 193.1.*.* or 193.1.217.* . In this case the program will scan the specified range of addresses and display all entries found.

 

 

Domain Queries

 

If you want to query a domain registration database, enter a domain name and hit the Enter key (in which case the application will attempt to guess whether you entered an IP address / hostname or domain), or click on the Query arrow button and select As Domain. The examples of valid domain names are yahoo.com, volvo.se, or ford.co.uk. Don't use the "www" prefix in your domain queries; for example www.micorsoft.com is not a valid domain query (albeit a valid hostname query).

 

 

Dual Queries

 

Sometimes you may want to find out the information on the IP address and domain name at the same time. For example, you can enter wikipedia.org and query this data as an IP address / hostname (to find out where the server is located) and as a domain (to find out who owns this domain). In this case, click on the Query arrow button and select As IP / Hostname and Domain.

 

 

Custom Queries

 

If you need to query a non-default whois server or make a special query, click View => Whois Console from the menu, or click Query button and select Custom Query.

 

 

Clipboard Queries

 

If you would like to query information located on the clipboard, click Query => Clipboard and select the preferred query type. This option is available in both main window and tray icon menus. The following options are available:

 

As IP address – select this option if you want to query the clipboard text as an IP address.

As Domain – select this option if you want to query the clipboard text as a domain.

 

When selecting any of the query types above, SmartWhois will perform the respective query for the first word found in the clipboard text.

 

As Text Containing IP Addresses – if you select this option, all IP addresses in the clipboard text will be processed regardless of their arrangement.

As List of IP Addresses / Hostnames – clipboard text will be processed as a list of IP addresses or hostnames. The first word on every line will be processed as IP address or hostname. This option is suitable for processing log files.

As List of Domains – this option is similar to the one above, except that the clipboard text will be processed as a list of domains.

 

In case the program window is inactive, you will still be able to perform queries by using hotkeys that can be assigned to any of the above-mentioned commands. Please see the Configuring SmartWhois chapter for more information on using hotkeys. Please note that hotkeys are disabled by default.

 

 

Window Queries

 

To query information located in the active window, right-click the SmartWhois icon located in the tray and select Query => Current Window. Next, select the desired query type.

 

The following options are available:

 

As IP address – select this option if you want to query the contents of the active window as an IP address.

As Domain – select this option if you want to query the contents of the active window as a domain.

 

When selecting any of the query types above, SmartWhois will perform the respective query for the first word found in the window.

 

As Text Containing IP Addresses – if you select this option, all IP addresses in the window will be processed regardless of their arrangement.

As List of IP Addresses / Hostnames – window contents will be processed as a list of IP addresses or hostnames. The first word on every line will be processed as IP address or hostname. This option is suitable for processing log files.

As List of Domains – this option is similar to the one above, except that the text will be processed as a list of domains.

 

If you need to process just a part of the text in the window, highlight it before performing the query. In case the program window is inactive, you will still be able to perform queries by using hotkeys that can be assigned to any of the above-mentioned commands. Note: this option is available for windows that support standard system text extraction methods only. Please see the Configuring SmartWhois chapter for more information on using hotkeys. Please note that hotkeys are disabled by default.
