You can also get a copy of the file by using following command on your YSFGateway-computer (in new format):
wget -O YSFHosts.txt https://register.ysfreflector.de/export_csv.php
Following url-parameters are provided:
?noresolve=1 - delivers ip-addresses instead of hostnames
?net=internet (or not added) - delivers reflectors present at the internet
?net=hamnet - delivers reflectors present at hamnet
?net=both - delivers reflectors present at hamnet and internet (so you get a list of all reflectors online on both networks)
