System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.当下，一家老小敬献各样贡品，再次鞠躬后退出祠堂。The third is that due to the low sense of scene in online learning and the weak restriction on students, the completion rate of students may be relatively low.当年，假玉米进门，秦枫和云影就在京城，张家当然要仔细检查了，却是毫无异样。大苞谷听说老王爷生病后，当时拔脚就走了，只跟英王世子说了一声。
