Another alternative:

Code:

awk '!/01:AF:55:F6:B0:23/ && ORS=RT' RS="}" dhcpd.conf

Well, the first thing that I would look for is some kind of an existing parser for this kind of information – someone who solved this problem and who posted their solution, say, on GitHub.

Otherwise, I probably would build a tool in a fully-equipped language such as Perl, and I might consider going so far as to use an actual parser such as Perl's Parse::RecDescent tool.

Note that this approach is "actual parsing," with a grammar for the specification language that you might encounter.
