What is bost?

A very simple "host" implementation by Avraham Lembke blambi@chebab.com It is not meant to be a full host replacement etc just translate hostname to a IP.

One good think on how its implemented is that it follows all the normal libc lookup's etc for your system so you can use it to test NSS or other configuration that changes your DNS lookups.

Where to get it or contact the author?

you can get it at http://blambi.chebab.com/software/bost/ And I'm contactable at blambi@chebab.com

Note on ranges

By choice the ranges are limited to a maximum of /24


For a single host

$ bost host

For an IP address: $ bost


$ bost 2001:6b0:17:f0a0::b3

For N hosts

$ bost host1 ... hostN

For a subnet/range

$ bost

Another range

$ bost

Its simple.. But there is currently no range support for IPv6 addresses.

current options are:
  -h, --help     Show help
  -d, --double   enable double check
  for example "bost -d foo" would output both the ip(s) of foo
  and the hostname(s) for the ip(s).


Just want to give big thanks to all people who have contacted me with bug reports and/or feedback.
