Host

Host is a command prompt Windows utility ported from FreeBSD Host utility. Host looks for information about Internet hosts. It gets this information from a set of interconnected servers that are spread across the world. By Default, it simply converts Between host names and Internet addresses.However, with the [-d] or [-a] options, it can be used to find all of the information about this host that is maintained by the domain server (A, MX, NS records, TTL). The arguments can be either host names or host numbers. The program first attempts to interpret them as host numbers. If this fails, it will treat them as host names. A host number consists of IPv4 dotted Decimal Quad (127.0.0.1). A host name consists of names separated by dots, e.g. www.itsamples.com.
