Hi redse171,

Its very simple

Code:
$ awk '/^@/{s = ($0~ip) ? 1 : 0}s' ip="192.2.3" file

/^@/{.. --> Search for line which starts with @

s = ($0~ip) ? 1 : 0 --> Once @ is found, check whether line contains ip string/pattern which we are searching for, if pattern is found on line, s will be 1 (true) else s will be 0 (false)

..}s --> Print line whenever s is 1 (true)
