關於xp反制系統的ip???

就是這個ip 239.255.255.250 port忘了,好像1999吧
發生於xp開完機剛連上網路及開ie時由norton firewall 2002所攔截到的位址
反查ip([url]http://www.arin.net/cgi-bin/whois.pl[/url])來源得知以下資料

如題如示,有誰知道那是誰家的ip呢?M$的嗎?我只知在美國加州
如果真的是M$的話,我看大家就自己看著辦吧,懂的我的意思吧
煩請大家一起來查一查,測一測吧..

備註:我已經依版友建議灌了ANTI-SPY除掉那些東東囉,AND MSN MESSAGE也沒自動開囉
以及DI-704硬體防火牆沒擋到那個PORT,我確定沒開那個PORT,還有MCADEE FIREWALL
完全沒反應(雖然是我意外中),還有確定由VSHOST.EXE所送出.
