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

(With obvious sanitization.)

What gives?
