Frequently Asked Questions

  • IP address is the Internet Protocol (IP) address given to every computer connected to the Internet. An IP address is needed to route information much like a street address or PO box is needed to receive regular mail. Example: 66.46.181.116
  • Domain name is a text name which a computer network registers. The domain name is used to give computers text names rather than using the numeric IP addresses. This like getting a vanity phone number that spells out a word to make it easy to remember. Domain name example: WebsiteBuilders.com
  • Computer (host) names are names given to individual computers. Each host name corresponds to an IP address. Host names and domain names are optional and everything will work fine with using just IP Addresses. Examples of host names: www.consumer.net mail.consumer.net Cust149.tnt3.sfo3.da.UU.net

Sends signals (packets) to another computer on the Internet to see if they send a return or an ‘echo.’ If all the signals ‘timeout’ the computer may be disconnected from the Internet or at least unreachable from the Consumer.net server. This feature only checks a computer connected to the Internet, it cannot verify the validity of an e-mail address. It also cannot check a specific web page, but you can check the main server to see if it is connected (www.whoishostingthis.com/hosting-reviews/ is not valid, but www.whoishostingthis.com is valid).

If an IP address is input this converts into a computer host name. It will also do the reverse process if a computer name is entered. This function has nothing to do with looking up e-mail addresses.

A computer name may or may not be ‘fully qualified domain name.’ This means that the computer is part of Internet registration system and the name can be converted both ways. Example: www.consumer.net converts to 209.207.246.160. It is also possible to give the computer a non-registered name such as ‘JOE.’ In this case the result of a lookup on the IP address would be ‘JOE’ but a lookup on ‘Joe’ will not give the IP address. This feature only looks up IP addresses or computer name, it will not look up e-mail addresses or web pages.

Traces the route through the Internet from Consumer.net to the destination computer. The signal generally goes from a computer to the Internet Service Provider (ISP) and then to their provider until it reaches a ‘backbone’ provider. This could take one or many steps. It then eventually transfers to the destination ‘backbone’ provider and reverses the process to the destination computer. This feature only checks a computer connected to the Internet, it cannot verify the validity of an e-mail address. It also cannot check a specific web page (blogging.com/how-to-start-a-blog/ is not valid but blogging.com is valid). Note that a traceroute may follow a completely different path as compared to downloading web pages or sending e-mail.

Program checks domain name and searches for the registration records for that domain based on the top level domain (.com, .uk. .au, etc.). To find information on a top level domain enter the domain ending such as “com” “uk” “ro” “biz” etc. This tool cannot look up who owns an e-mail address, just who registered a domain name.

Active domains have a configuration file stored in their nameservers. This file gives information about what IP addresses are mapped to computer names. Example: www.consumer.net converts to 209.207.246.160. It also provides information about which mail server a domain uses (Mail eXchanger or MX record). Example: Network-Tools.com used the mail.onsumer.net mail server. A graphical explanation of how DNS works. You can determine that a domain name uses a specific mail server but you cannot determine any additional information about an e-mail address. The administrator of the mail server would have that information.

Express Trace – Input: IP address or host name

(no http://, it is included automatically). This displays the header of a web page. This is information passed with with a web page that is not normally displayed by a standard browser. Depending of the type of web server being contacted, the information could include the type of web server software being used and information about the web page or graphic being accessed. This could include such things as file size, file creation date, error messages, etc. To see the headers sent by your web browser click here.

This can detect bad e-mail addresses. It checks syntax, checks if the domain is configured to accept e-mail, and then checks the e-mail server. Passing this test does not ensure an e-mail address exists but it can be used to detect bad addresses in many cases.

Convert Base 10 to IP – IP addresses can be converted to a “base 10” number. Spammers often use this in URL’s. Example: http://123456789/. If you wish to trace a URL like this just input the number “123456789” and check the “Base 10” button. It will convert the number to a standard IP addresses. If the URL contains “@” ignore everything to the left. http://[email protected]/ is the same as http://123456789/

A standard IP is “base 256.” To convert 66.46.55.116 to base 10 the formula is:

66 x (256) 3 + 46 x (256) 2 + 55 x (256) 1 + 116 = 1110325108

DNS Server – Choose the DNS server to use for the DNS lookup function. This can be used to query a specific nameserver. This is convenient to see if each of your nameservers has the proper configuration for the domain entered. This setting does not affect the DNS server used by the Lookup and Traceroute functions.
