 When the default registry is used in a package-lock or shrinkwrap it has the special meaning of "the currently configured registry". If you create a lock file while using the default registry you can switch to another registry and npm will install packages from the new registry, but if you create a lock file while using a custom registry packages will be installed from that registry even after you change to another registry.
