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 -.Dq Fl t -or -.Dq Fl a -options, it can be used -to find all of the information about this host that is maintained -by the domain server. -.Pp -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) or IPv6 raw address (::1). -A host name consists of names separated by dots, e.g. topaz.rutgers.edu. -Unless the name ends in a dot, the local domain -is automatically tacked on the end. Thus, a Rutgers user can say -.Pp -.D1 Ic host topaz -.Pp -and it will actually look up "topaz.rutgers.edu". -If this fails, the name is tried unchanged (in this case, "topaz"). -This same convention is used for mail and other network utilities. -The actual suffix to tack on the end is obtained -by looking at the results of a -.Xr hostname @CMD_EXT@ -call, and using everything -starting at the first dot. (See below for a description of -.Sx CUSTOMIZING HOST NAME LOOKUP . ) -.Pp -The first argument is the host name you want to look up. -If this is a number, an -.Dq inverse query -is done, i.e. the domain -system looks in a separate set of databases used to convert numbers -to names. -.Pp -The second argument is optional. It -allows you to specify a particular server to query. If you don't -specify this argument, the default server (normally the local machine) -is used. -.Pp -If a name is specified, you may see output of three different kinds. -Here is an example that shows all of them: -.Pp -.D1 Ic % host sun4 -.Dl sun4.rutgers.edu is a nickname for ATHOS.RUTGERS.EDU -.Dl ATHOS.RUTGERS.EDU has address 128.6.5.46 -.Dl ATHOS.RUTGERS.EDU has address 128.6.4.4 -.Dl ATHOS.RUTGERS.EDU mail is handled by ARAMIS.RUTGERS.EDU -.Pp -The user has typed the command -.Dq Ic host sun4 . -The first line indicates that the name -.Dq Li sun4.rutgers.edu -is actually a nickname. The official host name is -.Dq Li ATHOS.RUTGERS.EDU . -The next two lines show the -address. If a system has more than one network interface, there -will be a separate address for each. The last line indicates -that -.Li ATHOS.RUTGERS.EDU -does not receive its own mail. Mail for -it is taken by -.Li ARAMIS.RUTGERS.EDU . -There may be more than one -such line, since some systems have more than one other system -that will handle mail for them. Technically, every system that -can receive mail is supposed to have an entry of this kind. If -the system receives its own mail, there should be an entry -the mentions the system itself; for example, -.Pp -.D1 Li XXX mail is handled by XXX -.Pp -However, many systems that receive -their own mail do not bother to mention that fact. If a system -has a -.Dq Li mail is handled by -entry, but no address, this indicates -that it is not really part of the Internet, but a system that is -on the network will forward mail to it. Systems on Usenet, Bitnet, -and a number of other networks have entries of this kind. -.Sh OPTIONS -There are a number of options that can be used before the -host name. Most of these options are meaningful only to the -staff who have to maintain the domain database. -.Bl -tag -width Fl -.It Fl w -This causes -.Ic host -to wait forever for a response. Normally -it will time out after approximate one minute. -.It Fl v -Use "verbose" format for printout. This -is the official domain master file format, which is documented -in the man page for -.Xr @INDOT@named @SYS_OPS_EXT@ . -Without this option, output still follows -this format in general terms, but some attempt is made to make it -more intelligible to normal users. Without -.Dq Fl v , -any "a", "mx", and "cname" records -are written out as "has address", "mail is handled by", and -"is a nickname for" (respectively), and TTL and class fields are not shown. -.It Fl r -Turn off recursion in the request. -This means that the name server will return only data it has in -its own database. It will not ask other servers for more -information. -.It Fl d -Turn on debugging. Network transactions are shown in detail. -.It Fl s -Chase signatures back to parent key (DNSSEC). -.It Fl t Ar querytype -Allows you to specify a particular -.Ar querytype -of information -to be looked up. The arguments are defined in the man page for -.Xr @INDOT@named @SYS_OPS_EXT@ . -Currently-supported types include: -.Dq Cm a , -.Dq Cm aaaa , -.Dq Cm ns , -.Dq Cm md , -.Dq Cm mf , -.Dq Cm cname , -.Dq Cm soa , -.Dq Cm mb , -.Dq Cm mg , -.Dq Cm mr , -.Dq Cm null , -.Dq Cm wks , -.Dq Cm ptr , -.Dq Cm hinfo , -.Dq Cm minfo , -.Dq Cm mx , -.Dq Cm uinfo , -.Dq Cm uid , -.Dq Cm gid , -.Dq Cm unspec . -Additionally, the wildcard, which may be written -as either -.Dq Cm any -or -.Dq Cm * , -can be used to specify any (all) of the above types. -Types must be given in lower case. -Note that the default is to look first for -.Dq Cm a , -and then -.Dq Cm mx , -except that if the verbose option is turned on, the default is only -.Dq Cm a . -The -.Dq Fl t -option is particularly useful for filtering information returned by -.Ic host ; -see the explanation of the -.Dq Fl l -option, below, for more information. -.It Fl a -.Dq all ; -this is equivalent to -.Dq Fl v Fl t Cm any . -.It Fl l -List a complete domain; e.g.: -.Pp -.D1 Ic host -l rutgers.edu -.Pp -will give a listing of all hosts in the rutgers.edu domain. The -.Dq Fl t -option is used to filter what information is presented, as you -would expect. The default is address information, which also -include PTR and NS records. The command -.Pp -.D1 Ic host -l -v -t any rutgers.edu -.Pp -will give a complete download of the zone data for rutgers.edu, -in the official master file format. (However the SOA record is -listed twice, for arcane reasons.) -.Pp -.Sy NOTE : -.Dq Fl l -is implemented by -doing a complete zone transfer and then filtering out the information -the you have asked for. This command should be used only if it -is absolutely necessary. -.El -.Sh CUSTOMIZING HOST NAME LOOKUP -In general, if the name supplied by the user does not -have any dots in it, a default domain is appended to the end. -This domain can be defined in -.Pa /etc/resolv.conf , -but is normally derived -by taking the local hostname after its first dot. The user can override -this, and specify a different default domain, using the environment -variable -.Ev LOCALDOMAIN . -In addition, the user can supply his own abbreviations for host names. -They should be in a file consisting of one line per abbreviation. -Each line contains an abbreviation, a space, and then the full -host name. The name file must be contained in the -.Ev HOSTALIASES -environment variable. -.Sh ENVIRONMENT -.Bl -tag -width "/etc/resolv.conf " -compact -.It Ev HOSTALIASES -Name of file containing -.Pq Ar host alias , full hostname -pairs. -.El -.Sh FILES -.Bl -tag -width "/etc/resolv.conf " -compact -.It Pa /etc/resolv.conf -See -.Xr resolver @FORMAT_EXT@ . -.El -.Sh SEE ALSO -.Xr @INDOT@named @SYS_OPS_EXT@ , -.Xr resolver @FORMAT_EXT@ . -.Sh BUGS -Unexpected effects can happen when you type a name that is not -part of the local domain. Please always keep in mind the -fact that the local domain name is tacked onto the end of every -name, unless it ends in a dot. Only if this fails is the name -used unchanged. -.Pp -The -.Dq Fl l -option only tries the first name server listed for the -domain that you have requested. If this server is dead, you -may need to specify a server manually. E.g., to get a listing -of foo.edu, you could try -.Pp -.D1 Ic host -t ns foo.edu -.Pp -to get a list of all the name servers for foo.edu, and then try -.Pp -.D1 Ic host -l foo.edu xxx -.Pp -for all -.Dq Ic xxx -on the list of name servers, until you find one that works. |
