The 'starts with' and 'ends with' are literal strings, not numeric values. This means that you could get away with having a single 'starts with' and include the first 3 parts to represent a range.
For example, 'IP Address' starts with '66.6.147' would include all ranges from 66.6.47.0 to 66.6.47.255. You could get more granular by including another digit in subsequent lines if you'd like.
