In the process of DNS resolution, the client initiates a query request, and the DNS server may need to make additional queries to complete the resolution process and give a response, which will consume certain computing and network resources. If an attacker uses a large number of controlled hosts to continuously send resolution requests for different domain names, the cache of the DNS server will be continuously refreshed, and the failure of a large number of resolution requests to hit the cache will cause the DNS server to consume additional resources for iterative queries, which will greatly increase the resource consumption of the DNS server.男孩与女孩萍水邂逅，从此杳无音讯……却留下了一生的约定。电视剧《钢铁人》是的男子讲述一个心灵遭受创伤、在愤怒和伤痛的时候从身体爆发出尖锐金蜀的利器，并跟一个爱管闲事的女人发生爱情的故事。"Because the artillery suddenly 'dumb fire', Later, it was said that it was the same as position 169, because the ammunition consumption was too large and too many shots would be supplied for a while.

The entire position 142 trembled under the shelling, At last, I felt that the ground under my feet would be overturned. Now think about it. If it weren't for the artillery comrades' hard support for us, the dozen or so people and the guys in our hands at that time could not withstand the attack of so many strange things. If they were called to rush up, they would have to tear us up and chew us up.陈启看向林白，说道：有没有兴趣制作《笑傲江湖》这个游戏？被你看出来了。摆脱了几大门派的高手，俞莲舟和张翠山一家三口开始赶回武当山。故事发生在太行山深处、王莽岭脚下的沟里村。山修路，凿穿王莽岭的工程5年前进了100米。小庄计算这样干还得用80年，老支书听后惊呆了。小庄为竞选村长和老支书产生了误会。 　　小庄带领大家集资买电钻，新的工程开始了。老支书重新认识了小庄，却为排险石而牺牲。 　　除夕夜小庄一人守在工地，菊香为他送来了饺子，二人和好。结婚时，村民认为菊香名声不好，没人前来祝贺，菊香流下凄楚的眼泪。 　　小庄为动员村民上山修路，动手打了表弟大保。大保娘称赞小庄打得对，教育了儿子大保。一次爆破中大保重伤牺牲。 　　小庄的人格力量感动了沟里人，人们纷纷上山修路。路通了，全村人第—次看到了汽车进山，小庄来到了老支书和大保的坟前，默默地告慰在天之灵。
