I was talking about these two (redundant?) definitions: tools/hipdnsproxy/hipdnsproxy.in (l:20) +HIT_RE = re.compile(r'[^0-9a-f:](?P<hit>2001:1[0-9a-f]:[0-9a-f:]*)[^0-9a-f:]') tools/hipdnsproxy/hosts.py (l:324): +HIT_RE = re.compile(r'^2001:1[0-9a-f]:[0-9a-f:]*$') After the "2001" there can be some zeroes before the "1". -- https://code.launchpad.net/~ptman/hipl/methods-to-functions/+merge/102584 Your team HIPL core team is subscribed to branch lp:hipl.
