Look strange but match the Python documentation for re.findall:
"If one or more groups are present in the pattern, return a list of
groups; this will be a list of tuples if the pattern has more than one
group"
you must use this RE for your example to match what you expect:
ipre=re.compile("(?:[0-9]{1,3}\.){3}[0-9]{1,3}")
but using re.finditer is IMHO better.
Cheer,
