PTR records are commonly used by mail servers and anti-spam systems to validate connecting IPs — their absence can affect deliverability to strict receivers.
Spamhaus has listed this IP (XBL: 僵尸网络 / 被攻陷主机), which suggests it has been involved in spam or compromised activity. While a listing does not guarantee ongoing abuse, it can impact deliverability and trust score. Balance risk-control with normal access patterns: standard rate limiting plus CAPTCHA on sensitive flows.
