You might check for existing relays in their system. This Robtex seems to have much of their network, which they appear to lease from other providers: https://www.robtex.com/en/advisory/dns/cr/crservers/ And while they advertise many network blocks, it appears it's all slices of just a few large allocations: http://www.cidr-report.org/cgi-bin/as-report?v=4&as=AS3790 http://www.cidr-report.org/cgi-bin/as-report?v=4&as=AS2385 You can download CSV of all relays from https: // torstatus dot blutmagie dot de and look for matches. Otherwise, call or email them and ask how they feel about Tor exits. Hosting is competitive and if you run a relay with proper contact info and reverse DNS they might not mind. Ask them to automatically forward any complaints they receive to you.
