Local Name Resolution in Disconnected State

Domain Name System (DNS) is designed to transform human readable Internet addresses to corresponding Internet Protocol (IP) addresses. Current DNS relies on hierarchical infrastructure. It could be useful to use services provided by DNS in Local Area Networks (LAN) when there is no Internet connectivity. This can be caused by temporary network errors. There is proposals on using Distributed Hash Table (DHT) based systems to replace DNS or to give it more flexible counterpart. DNS caching is discussed in this paper, because it speeds up resolving process and makes it more reliable. In the case of local name resolving in disconnected state, this paper looks into software solutions for implementing local DNS-caches on local machines.
