I've got a .txt file similar to the one below, except mine has thousands of blocks similar to the ones shown.
My goal is to find all of the 172.* entries that are NOT of a particular MAC type (say 00:0d:97:blah) and remove them. Resulting in a new file containing all but those text blocks, block being defined by 'lease x.x.x.x through next '}'. Please HELP me....
