Cloudflare BYOIP
Get Cloudflare's security and performance while using your own IPs.
When you use Cloudflare as a reverse proxy, Cloudflare responds to DNS queries for proxied records with Cloudflare-owned IP addresses1. For some organizations, it is important to keep their website or application associated with IP addresses they already own rather than using Cloudflare's.
With Bring Your Own IP (BYOIP), Cloudflare announces your IP prefixes in all our locations. Use your IPs with Magic Transit, Spectrum, CDN services, or Gateway DNS locations and dedicated egress IPs.
Learn how to get started.
Control whether traffic destined for a given IP address is routed to Magic Transit, CDN, or Spectrum.
Specify which IP addresses should be mapped to DNS records when they are proxied through Cloudflare.

Without BYOIP, when your domain's records are
proxied, Cloudflare responds with a Cloudflare-owned anycast IP address.
