What is spoofing DNS?

DNS is an abbreviation of the domain name system, a methodology for conversion between domain names such as wisegeek.com , and IP (Internet protocol) addresses, which are a number of four to three digits, separate points. All computers and devices connected to the Internet have an IP address, and DNS prevents people from having to remember numerical chains by allowing you to replace people's words instead. Spoofing is a deceptive practice that is used to make the goal of mistake one thing for another. Spoofing is carried out with e -Maly to be other than the actual sender and websites that use all possible means to indicate that they represent a real individual or organization other than the one that actually created it. Spoofing DNS is a practice to perform the DNS address to a different IP address than the one with which it is actually connected.

Spoofing DNS can be done for legitimate or illegitimate purposes. Cisco Systems ProvideE on the routers of the DNS spoofing function to allow the router to act as a DNS server, while the ISP interface settings are not functional. The explicit understanding is that the router returns to the usual task to give questions to DNS servers as soon as possible. However, spoofing DNS is also performed for fraud purposes and is sometimes used in connection with Spoofed sites with the intention of getting users to believe that he or she landed on the intended site. This type of setting often uses a site where users enter usernames and passwords, account numbers, and other information that can be used for profit.

spoofing DNS is different from the kidnapping of DNS, although the kidnapping of DNS will also take the user to a site other than the one that has tried to achieve. The difference is Hat DNS does not necessarily try to deceive the user of the URL to which it was ordered. For example, it was used by some ISP (Internet service providers) in the event of a NXDOMAIN error - that is, if the URL is not found - probably because it is not.Atna, so instead of an error message, the user sees a replacement page, usually with advertising, usually with advertising, but doesn't look like a site trying to achieve.
