Comments can only start at the beginning of a line, so putting #dynamic at the
end of the line might not work. You can vary whitespace if you want to
distinguish between manual and dynamic Addresses. To top you, the following
script that remembers the last 3 dynamic addresses and does not overwrite the
host config file when something goes wrong:

#!/bin/sh
file=/etc/tinc/$NETNAME/hosts/$NODE
grep -Fq "Address  =  $REMOTEADDRESS" $file && exit 0
grep -Fv "Address  =  " $file > $file.new &&\
echo "Address  =  $REMOTEADDRESS" >> $file.new &&\
grep -Fm 2 "Address  =  " $file >> $file.new &&\
mv $file.new $file
