Anonymous Monk,
Since it doesn't sound like you want to know how to do it and more "is it possible" I am inclined to answer. There are many reasons lots of IP addresses could look like they are coming from the same one or the reverse, one IP could look like it is coming in as many. In fact, lots of large corporations and government agencies use proxies for this very purpose.

TCP connections are a two way street. Spoofing an IP address means making it look like those packets are coming from somewhere they are not. There isn't any point in spoofing an IP address if you need to see the packets coming back - since they are going to that other IP (you are working blind). And if that other IP responds back with a RST packet as it might do - you've been had.

You can use several tools such as whois to find out who the IP addresses are registered to. The IPs may all be affected with a virus that is designed to harvest passwords or something. And finally, yes - Perl could be used to create an IP spoofing tool though a lot of factors mentioned above would have to be considered.

Cheers - L~R

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
