The documentation gives the worked example host 111.225.148.250 -> bytespider-111-225-148-148.crawl.bytedance.com. The same page lists ten IPv4 /24 ranges inline (110.249.201.0/24, 110.249.202.0/24, 111.225.148.0/24, 111.225.149.0/24, 220.243.135.0/24, 220.243.136.0/24, 220.243.188.0/24, 220.243.189.0/24, 60.8.123.0/24, 60.8.151.0/24); no machine-readable JSON or TXT IP range file is published.",
