[CentOS] Nagios NRPE IPv6

On my network management server I have

Name        : nagios-plugins-nrpe
Arch        : x86_64
Version     : 2.13
Release     : 1.el6
Size        : 38 k
Repo        : installed
From repo   : epel

To my dismay I noticed that this doesn't seem to support IPv6:

[ts at bombur ~]$ host galadriel.example.com
galadriel.example.com has IPv6 address 2001:db8:f004:8::32
[ts at bombur ~]$ /usr/lib64/nagios/plugins/check_nrpe -n -H
galadriel.example.com
Invalid host name 'galadriel.example.com'
[ts at bombur ~]$ /usr/lib64/nagios/plugins/check_nrpe -n -H
2001:db8:f004:8::32
Invalid host name '2001:db8:f004:8::32'
[ts at bombur ~]$

(With obvious sanitization.)

What gives?
