1、如果黑客給我發了一封郵件，我不小心打開，但裏麵沒有什麽鏈接，就是幾個字母。如果我沒回信，隻是打開郵件，黑客能因此得到我的IP地址嗎？
Probably not if you didn't click any link or attachment inside the email.
2、是不是得到我的IP地址就可以入侵我的電腦了？如果答案是肯定的，我該怎麽辦？
No.
3、前些日子一台電腦中木馬病毒，被殺除。還有什麽隱患或漏洞，我需要注意？
Your PC should be ok If it's removed.
4、是不是家裏每台電腦的IP地址都不一樣？還是都一樣（用同一網絡）？
To the external world, 家裏每台電腦的IP地址都一樣. Inside your home network, 家裏每台電腦的IP地址(private IP)都不一樣. Your home router is doing the external IP address to internal private IP address translation. The external IP address is assigned by your ISP like ATT, Verizon, Comcast etc. The internal used private IP addresses are assigned by your router.
5、如果不換網絡，怎樣才能換一台電腦的IP地址？
The external IP address assignement depends on your ISP. You'll get a new external IP address if you turn of your modem for a few hours or even a day, depending on your ISP.
Possible.
