Three files are created as a resultof running .PN htable:.IR hosts ,.IR networks ,and.IR gateways .The .I hostsfile is used by the .PN gethostent(3n)routines in mapping host names to addresses.The.I networksfile is used by the.PN getnetent(3n)routines in mapping network names to numbers.The.I gatewaysfile is used by the routing daemonin identifying passive Internet gateways;see.PN routed(8c)for an explanation..PPIf any of the files.IR localhosts ,.IR localnetworks ,or.I localgatewaysare present in the current directory,the file's contents is prepended to theoutput file without interpretation.  Thisallows sites to maintain local aliases andentries which are not normally present in themaster database..PPThe.PN htableprogram is best used in conjunction with the.PN gettable(8c)program which retrieves the NIC database from a host..SH RestrictionsDoes not properly calculate the.I gatewaysfile..SH See Alsointro(3n), gettable(8c)
