add blank lines after word MAC (sed/awk or perl??)

[NNTP]

I have a file with the following data

192.168.60.161 DOMAINNAME-POWER 03U
192.168.60.161 DOMAINNAME-TEMP 1eU
192.168.60.161 MAC 00-xy-zz-07-bd-8a
192.168.60.179 DOMAINNAME-abacdf 00U
192.168.60.179 DOMAINNAME 00U
192.168.60.179 DOMAINNAME-abacdf 20U
192.168.60.179 DOMAINNAME 1eU
192.168.60.179 MAC 00-xy-8b-1c-08-c7
192.168.60.198 DOMAINNAME-abcd 00U
192.168.60.198 DOMAINNAME 1cU
192.168.60.198 DOMAINNAME 00U
192.168.60.198 DOMAINNAME-abcd 20U
192.168.60.198 DOMAINNAME 1bU
192.168.60.198 DOMAINNAME 1eU
192.168.60.198 DOMAINNAME 1dU
192.168.60.198 MAC 00-zz-aa-bb-8f-35


what I want to do is add blank line after MAC entry for each IP. I am
confortable with awk/sed but can't seem to fig. this out.

do I need perl? or can sed/awk do this?

I don't understand the reference to this mythical language called sed/awk.
Wouldn't it make just as much sense to ask if it could be done in
Fortran/Python?

Anyway, in AWK (2 liner):

1
/MAC/ {print ""}

sed -e '/MAC/G' yourfile
