A complete guide to the splitdns desktop app: credentials, origin settings, domain configuration, step-by-step setup, health checks, and teardown. Configure routing through Cloudflare overseas and another CDN in China with a guided, validated workflow.
I keep the main domain on Cloudflare and delegate just one subdomain to DNSPod for regional routing: mainland China uses EdgeOne, while overseas traffic stays on CF CDN through Cloudflare for SaaS. Includes full setup steps and pitfalls to watch for.
I tested netcup Nuremberg and OVH Hillsboro on the US West Coast against the same 33 global targets in the same time window, comparing international connectivity using path inflation ratios: one relies on direct peering at internet exchanges, the other on its own long-haul backbone.
Netcup VPS 500 G12 tested in Nuremberg: EPYC Genoa with 2 cores, 4G RAM, and a 125G disk; native German IP with full streaming access. Return routes use Arelion for China Telecom/Unicom and Core-Backbone → CMI for China Mobile.
