NEW! VGWhoIs (Fork by ViaThinkSoft)

For people who are researching holders of domains, e.g. because of legal issues or for people who are writing software which needs to find out which country is assigned to an IP it is hard to get a good source for whois information in plain text form. Most services either deny requests from bots, are hard to parse, are filtering email-addresses, limiting your amount of queries or do not delegate to the correct whois server (e.g. Asian IPs are queried by the ARIN server instead of APNIC). It is possible to use the Linux command "whois" for this purpose, but this is only possible if you are using Linux and if you have the permission to access this command. ViaThinkSoft has a good alternative to provide a free access whois server. Robots as well as normal users are allowed. This service mainly aquires its informations from an improved version of Debian Linux's gwhois command and improves the formatting in further treatment. All tools are IPv6 capable.

ViaThinkSoft offers the following tools:

• (VG)WhoIs Lookup [IPv4, IPv6] - Use the web-interface to query a domain, IP-address, ASN or OID (starting with oid:) etc.:
  
  https://whois.viathinksoft.de/whois/
  

  You can also send a whois query to whois://whois.viathinksoft.de.

• (VG)WhoIs Attribute Lookup [IPv4, IPv6] - query a single attribute of the WhoIs result:
  
  https://whois.viathinksoft.de/attrib.php?handle= &attrib=
  

• Country-Lookup [IPv4, IPv6] which uses the first occourence of "Country" in the WhoIs of the IP (if nothing was found or the hostname could not be resolved it outputs ??). Please note that domain names will most likely show the server's country and not the registrar's country (which is not easy to parse because every NIC has different WhoIs responses and/or is filtering). If the query fails, GeoIP and then hostip.info will be asked. Note that the country-resolution may be not correct.

• Abuse-EMail-Lookup [IPv4, IPv6] which uses the first occourence of "Country" in the WhoIs of the IP (if nothing was found or the hostname could not be resolved it outputs ?). Please note that domain names will most likely show the server's country and not the registrar's country (which is not easy to parse because every NIC has different WhoIs responses and/or is filtering). If the query fails, GeoIP and then hostip.info will be asked. Note that the mailbox-finding may be not correct.

• Reverse DNS-Lookup [IPv4, IPv6] Finds out the hostname for a given IP-address.
  
  https://whois.viathinksoft.de/reversedns/
  

• IP Resolution [IPv4, IPv6] - This script resolves any hostname to all available IPv4 or IPv6 addresses (A/AAAA DNS records). It is useful if you want to resolve an IPv6 and do not have the correct implementation to do this. The script outputs ??? if the address could not be resolved.

• Network description [IPv4, IPv6] - This script searches the network name / description or organisation name of that IP. The result is cached and valid for 1 month. If something fails, the output will contain ERROR: at the beginning.
  https://whois.viathinksoft.de/netname/
  

• Ping Lookup [IPv4, IPv6] which is useable if you assume that your ISP has a problem resolving a DNS entry (This page contains a VNag Interface):
  
  https://whois.viathinksoft.de/ping/?H=
  

• My IP-Address - Find out your IP address without any big overhead!

  https://whois.viathinksoft.de/myip

• Request-Data - Find out some other information about your request.

• Misc stuff

  • RIR COUNTRY statistics incl. sourcecode!
