Last updated on Nov 22, Humans access information online through domain names, like nytimes. Web browsers interact through Internet Protocol IP addresses. Each device connected to the Internet has a unique IP address that other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as Confusion Points. Consider the resolution of the domain name www. Assume that no resource records are cached anywhere across the DNS servers and that an iterative query mechanism is used in the resolution. The DNS resolver travels to the root server, then forwards to the top-level domain, then forwards to the second level domain, and obtains the IP address from the authoritative DNS server in the iterative query. There are 4-pairs involved in completely resolving the domain name. Additional Information. When a DNS server accepts and uses incorrect information from a host that has no authority giving that information, then it is called. It is the act of disguising a communication from an unknown source as being from a known, trusted source. Therefore when a DNS server accepts and uses incorrect information from a host that has no authority giving that information, then it is called DNS spoofing. Which one of the following protocols is NOT used to resolve one form of address to another one?
