How can you find all the IP addresses in a selected block of text with a javascript bookmarklet?

javascript:ipAddresses=document.getSelection().match(/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/g).join("<br>");newWindow=window.open('', 'IP Addresses in Selection', 'innerWidth=200,innerHeight=300,scrollbars');newWindow.document.write(ipAddresses)

javascript:alert(
  document.getSelection().match(/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/g)
  .join("n"))

/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/
/^([1-9][0-9]{0,2})+.([1-9][0-9]{0,2})+.([1-9][0-9]{0,2})+.([1-9][0-9]{0,2})+$/

javascript:document.write(document.getSelection().match(/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/g))

CmdUtils.CreateCommand({
    name: "findip",
    preview: function( pblock ) {
        var msg = 'IP Addresses Found<br/><br/> ';
        ips = CmdUtils.getHtmlSelection().match(/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/g);
        if(ips){
            msg += ips.join("<br/>n");
        }else{
            msg += 'None';
        }
        pblock.innerHTML = msg;
    },

    execute: function() {
        ips = CmdUtils.getHtmlSelection().match(/bd{1,3}.d{1,3}.d{1,3}.d{1,3}b/g);
        if(ips){
            CmdUtils.setSelection(ips.join("<br/>n"));
        }
    }
})
