Title Description Portal The problem is actually very interesting.First, according to the description of the topic the answer should be the combined length of all suffixes minus 22 LCPFirst figure out the sumTo find the SA and height, with two times the monotone stack can be found at a point of height as the minimum value of the longest intervalCan be found at this point as the demarcation point, the left and right sides of the interval 22 combination minimum must be the height of the current

Most DNS cache servers exist in small enterprises. they are not responsible for domain name resolution and are only used to help users query domain name information from other DNS servers. The queried information is saved locally to facilitate the next use of the domain name. it is valid to shorten the domain name query time and save the local information. The following is... information Most

The previous section mentioned some of the content of the recursive query, but said very little, but also very general, this section will be based on the principle and the case two aspects of DNS recursion and iterative query. Before that, we need to learn some background to better understand today's topic. In the Internet, a smooth resolution of a domain name is inseparable from two types of domain name servers, only by the two types of domain name

Recently found that a number of installation Win8.1 system users encountered Win8.1 application store and Updata Automatic Updates, the presence of the application store can not open and can not get automatic update information and so on. And these two kinds of problems, we can usually modify the DNS server address to be resolved, so the following article will be a detailed introduction to the next Win8.1 how to set up

Website optimization technology is always evolving. Today I re-read the previous front-end optimization notes and found that the section on YSlow Optimization 34 guidelines on reducing DNS lookups (reduce DNS lookups) should probably be revised. DNS as the foundation of the Internet Protocol, the speed of its resolution seems easy to be overlooked by site optimiz

Most of the network traffic is based on TCP/IP, while TCP/IP traffic is based on IP address, but in the real network access who is willing to use IP address, because the IP address we remember inconvenient.

For example, a string ababc First, regardless of the null character, all prefixes have a, AB, ABA, Abab, ABABC, where the true prefix has a, AB, ABA, ABAB In the same way, the suffix is understood, and the true prefix is the first (back) prefix that does not contain itself. The prefix function Next[j] refers to the longest true suffix of a string and also the substring length of its prefix. I'm not sure

I have understood this attack for a long time and do not understand what it means to "rebind. After A little understanding, I found that the attack principle is literal. Refresh the DNS A record and bind it to another address. In the following section, I reference the note of a fairy "To mount a DNS rebinding attack, the attacker need onlyRegister a domain name, such as attacker.com, and attractWeb tra defa
