 ### Can the anycast IP change over the lifetime of my Front Door?
 
 The frontend anycast IP for your Front Door should typically not change and may remain static for the lifetime of the Front Door. However, there are **no guarantees** for the same. Kindly don't take any direct dependencies on the IP.
