See this stackoverflow q and a Q- What is the LMhosts File and where is it stored?Ī- The LMhosts file is found on Windows machines and is used for NetBIOS name to IP address mapping similar to the hosts File. Common Questions and Answers Q- Is there a DNS cache on Linux?Ī- Not normally. See this Technet article for a more detailed look at nbtstat. To View the NetBIOS Name Cache use the nbtstat command nbtstat -c Note: The cache isn’t cleared automatically on Windows which is unusual for a cache. On Windows machines you can see the contents of the DNS cache and clear it using the ipconfig command. See here Viewing and Clearing the DNS Cache- Windows However SMTP, FTP and other traditional Internet protocols and application use hosts and DNS. On Windows machines, traditional NetBIOS application use NetBIOS name resolution methods before they use the hosts file and DNS. The name resolution order can also be affected by the type of application making the request. Windows specific name resolution methods are:Īpple specific name resolution methods are: Windows And Apple Name Resolution Methods However they also kept their old methods, and modified them to work over TCP/IP. Microsoft and Apple moved from their proprietary networking protocols and standardized on TCP/IP, and in doing so adopted the hosts file and DNS resolution methods. The Internet was built on Linux (Unix) and TCP/IP which used the hosts file and DNS as the main name resolution methods. Likewise Apple also had their own networking protocols and name resolution methods. They areĮarly Windows networks used the Netbeui (NetBIOS) protocol which had its own name resolution methods. There are three operating systems in common use on home and corporate networks. In Linux this is done in the /etc/ nf file. The order in which it tries this method is a host parameter that can be changed. Generally a host will try multiple methods until it succeeds or runs out of methods to try,and then it fails. There are several ways that the host machine can resolve a domain name. To do that it uses the the name resolution processes provided by the host machine. On computer and home networks when you type an Internet address into a web browser the web browser needs to convert that web address into an IP address.
