DNS caching is a vital aspect of computer, laptop, and desktop performance. It's like a digital memory, storing recent DNS lookups to accelerate future access to websites and services. This not only speeds up your device's response time but also conserves bandwidth by minimizing redundant reque...
Luckily, recursive DNS resolvers do not always need to make multiple requests in order to track down the records needed to respond to a client; caching is a data persistence process that helps short-circuit the necessary requests by serving the requested resource record earlier in the DNS ...
DNS服务器面临的安全问题主要包括DNS欺骗(DNS Spoofing)、拒绝服务(Denial of Service,DoS)攻击、缓冲区漏洞攻击、分布式拒绝服务攻击、缓冲区溢出漏洞攻击(Buffer Overflow)和不安全的DNS动态更新等。3.3.1 DNS欺骗DNS欺骗即域名信息欺骗,是最常见的DNS安全问题。当一个DNS服务器掉入陷阱,使用了来自一个恶意DNS服务器...
Operating System DNS Caching The DNS resolver at the operating system level is the last local place a DNS query searches for a record. Operating systems are built to handle these local queries using something called a stub resolver. When a stub resolver gets a query, it dives into its own ...
Recursive DNS resolver: A recursive DNS resolver is the DNS server that processes the initial request and connects with the higher-level authority for established domain details. Authoritative nameserver: Also known as a root server, these are a set of established servers that provide an authoritativ...
In addition to managing the authoritative DNS and deploying recursive resolvers (responsible for caching and data retrieval), managed DNS can provide businesses with: Automated DNS failover and disaster recovery Managed DNS features can distribute traffic across secondary DNS servers (using zone transfers...
