Hi, thank you for your swift reply! This morning I stumbled upon this post on the unix stackexchange (from 2 years ago): http://unix.stackexchange.com/questions/102660/hosts-file-is-it-incorrect-to-have-the-same-ip-address-on-multiple-lines
Like I said, I've been using the same ip address on multiple lines since a long time (mostly for readability and to easily comment & uncomment lines) on my local machines for a long time without running into issues. I just wanted to make sure this is quite trivial and should never cause any issues. I'm also making sure that the names itself only appear once in the whole file..
