Frequently Asked Questions

Q. Can I use SmartWhois if I'm behind a firewall or a proxy server?

A. Yes, SmartWhois supports SOCKS firewalls and HTTP/HTTPS proxy servers (they must support the CONNECT method). If your firewall is not SOCKS-compliant, you'll have to configure it to allow network traffic on TCP ports 43 and 80. Please refer to your proxy server's documentation or contact your network administrator for information on configuring (mapping) proxy ports. Also, see the Using SmartWhois From Behind a Firewall chapter of the help file for more detailed information.

Q. I made a query using wildcard, but the program's status bar displays "Connection timed out" before I get any results. How can I make it work?

A. Using wildcard queries usually takes longer to retrieve data than using normal queries. To handle this problem, you should set a longer timeout period (Settings => Options => Queries). For example, you can change the timeout period from 45 seconds to 100 seconds.

Q. Why do I get the "Connection timed out" or "Connection failed" errors?

A. There are several possible reasons:

· Your connection to the Internet is too slow or "fuzzy," which usually happens when you have a low quality telephone line. Try to reconnect to your ISP.
· The Whois server the program is connecting to is down. SmartWhois obtains information from official whois databases, and these databases are not in our control. So you'll have to wait until the server is up and running again, which normally doesn't take long.
· If you enabled IP address/hostname caching in the Options, the program might fail to connect to a Whois server if its IP address has recently changed. Click Clear Cache in Settings => Options => Cache => DNS.
· Your network environment does not permit outbound TCP connections on ports 43 and 80. This is often the case when you don't have direct Internet access, e.g. you are behind a corporate firewall, or if you installed a personal firewall with incorrectly configured packet-blocking rules.

Q. When running a batch query, I only get certain percentage of the domains / IP addresses processed. Why some of the records are unavailable?

A. Many whois databases temporarily or permanently ban an IP address after receiving a certain number of queries over a fixed period of time. To avoid being banned, we suggest that you use a great number of proxy servers for connecting to whois severs. SmartWhois is capable of selecting a random server from the proxy list every time the application connects to a whois server. This may help you avoid being banned. Please refer to the Using SmartWhois From Behind a Proxy / Firewall chapter of SmartWhois manual for more information on configuring proxy servers.

Q. Can I call SmartWhois directly from my application?

A. Yes. You can use the command-line interface to send an IP address or domain to SmartWhois and run the query. Please see the Command Line Options chapter of the manual for more information on command-line usage examples.

Q. My firewall software warns me that SmartWhois is "attempting to access the Internet." I am aware that some sites are able to track users by collecting the information sent by their programs via Internet. Why does SmartWhois "attempt to access the Internet"?

A. What alerts your firewall are the attempts to connect to Whois databases to fetch the requested records, and the attempts to connect to DNS serves to resolve IP addresses to hostnames. The primary function of the program is to obtain the most current records available from whois databases; therefore SmartWhois makes outbound connections on TCP ports 43 and 80 and UDP port 53. Additionally, the program may check for updates by contacting www.tamos.com (this functionality can be disabled). There are no other hidden activities. We don't sell spyware.

Q. When I click on the SmartWhois icon in the Microsoft Internet Explorer or Firefox toolbar, the program box flashes up briefly and then vanishes. Why this feature isn't working?

A. The SmartWhois plug-in window is displayed only when it is active, and it is automatically closed when the focus is moved to another window. Most likely you have a software running that is changing the focus and activates other windows, or always moves its window on top. We would suggest to close all other running applications one by one to see which one is affecting SmartWhois. Another reason for this behavior could be the mouse cursor settings on your computer. Certain mouse driver utilities allow you to configure the cursor to activate the window under the cursor, or even bring it to the foreground. When these features are enabled, they will prevent SmartWhois window from staying open.

Q. I can't see the owner information when querying Chinese or Japanese domains; I see gibberish instead of characters.

A. To see text in East Asian languages, you should install East Asian fonts in Windows. Open Control Panel => Regional and Language Options, select the "Languages" tab, and check the "Install files for East Asian languages" box.

Q. What are LOC records and are they supported by SmartWhois?

A. A LOC record stands for geographic location information: some domains and IP addresses may have a special DNS record that stores the object location coordinates (Latitude, Longitude, etc.). SmartWhois can query this information and generate a Google Map link to view the location of an object on the map.

Q. What are internationalized domain names and are they supported in SmartWhois?

A. An internationalized domain name (IDN) is an Internet domain name that contains one or more non-ASCII characters. Such domain names could contain letters with diacritics, as required by many non-English languages, or characters from non-Latin scripts such as Arabic, Hebrew, Chinese or Hindi. And, yes, SmartWhois supports IDN queries.

Q. IPv6 queries don't work for me. Is there anything I can do about it?

A. To successfully make IPv6 queries you need to have Windows XP or later operating system installed. If you're running Windows XP, the IPv6 support should be installed. To install it, open a Command Prompt window and execute the following command:

netsh interface ipv6 install

Note: IPv6 is not supported on Windows 2000 or earlier operating systems.
