IPNetInfo is a small utility that allows you to easily find all available information about an IP address.

• Resolve IP addresses: If you select this option, all IP addresses are converted back to the host name. The resolved host name is displayed in ' Resolved Name' column.
• Convert host names to IP addresses: If you select this option, all host names that you type will be converted to IP addresses. You can use this option if you want to know who owns the IP address of specific Web site (For example: If you type ' www.yahoo.com' , you' ll get the information about the IP address of Yahoo Web site)
• You should not select this option for message headers.
• Load only the last IP address: In most email messages, the last IP address in the message headers is the address of the computer that sent the message. So if you select this option for message headers, you' ll get the desired IP address in most cases (but not in all of them!). However, for finding the origin of unsolicited mail, it' s not recommended to use this option, because many spammers add fake headers and IP addresses in order to deceive the user who tries to trace them. When you try to trace the origin of unsolicited mail, you should examine all IP addresses that appears in the message headers.
