A bit off topic, but a best practice:

is to leave that last comma *on* the last element for lists like that.
What often happens is you go to add another "group" here, copy/paste the
last line and change it
my $VAR1 = {
'group1' => '10.100.27.52',
'group2' => '10.100.27.53',
'group3' => '10.100.27.54',
'group4' => '10.100.27.55',
'group5' => '10.100.27.56',
'group6' => '10.100.27.57' #Last element has no comma...
'group7' => '10.100.27.57' #Last element has no comma...
};
and now you have a syntax error. You can leave the last element's comma,
Perl will basically ignore it in building the hash (or array)
