Recursion

  1. When referring to computer programming, recursion refers to a function or subroutine that calls itself purposely or by mistake. Recursion is commonly performed to solve problems capable of being resolved by deduction; many numeric problems can often be resolved by recursion.
  2. When referring to a network or domain name servers, recursion refers to an available option that will enable or disable the ability of name servers sending requests from other name servers.

    Microsoft's DNS server recursion can be disabled by setting the below registry key to a value of 1.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentContolSet\Services
    + \DNS\Parameters.
