Issue #11499 has been updated by Daniel Pittman.

Status changed from Unreviewed to Accepted
Assignee set to Daniel Pittman

Turns out our validation is woefully wrong against a whole bunch of valid 
addresses.  Who would have thought that IPv6 and IPv4 validation are hard when 
you use a single regular expression?

Bug #11499: validation code for puppet resource host does not properly check if 
ip is valid
https://projects.puppetlabs.com/issues/11499

Author: Garrett Honeycutt
Status: Accepted
Priority: Normal

Target version: 
Affected Puppet version: 2.7.6
Keywords: 
Branch: 


It appears that we only check that the digits are [0-9] and period, while we 
should be doing an actual IP check

Attempting to use a letter. Fails as expected.
<pre>
[root@puppet ~]# puppet resource host junk.tld ip=1.2.3.a ensure=present
Could not run: Parameter ip failed: Invalid IP address
</pre>

Attempting to use a bad IP, which works and should not.
<pre>
[root@puppet ~]# puppet resource host junk.tld ip=10.10.10.10.10 ensure=present
notice: /Host[junk.tld]/ensure: created
host { 'junk.tld':
  ensure => 'present',
  ip     => '10.10.10.10.10',
  target => '/etc/hosts',
}
</pre>
