Merging IP ranges

In my first additions of IP ranges to institutions I have added the ranges as they are represented by RIPE, but in fact some of these ranges can be merged. For instance on University of Orléans (Q13334), the IP ranges '193.49.80.0/24','193.49.81.0/24','193.49.82.0/24','193.49.83.0/24' can be merged into '193.49.80.0/22'. I plan to merge automatically these ranges in the coming days. − Pintoch (talk) 20:57, 4 April 2017 (UTC)
