**Intel Assessment**
This IP belongs to DigitalOcean's cloud infrastructure in the London region. The endpoint hosts a legitimate web service with standard web hosting configuration. Moderate risk rating is driven by DNSBL presence and route instability rather than confirmed malicious activity. No immediate threat indicators suggest blocking; however, the DNSBL listings warrant monitoring. The associated domain (form.davidschristiancentre.org) should be verified if this IP appears in malicious activity contexts.
Recommendation: Monitor for increased threat signals before implementing blocking controls.
