Generate a clean LOA for announcing IP prefixes or an ASN through a carrier, datacenter or cloud provider. Everything stays in your browser, nothing is uploaded or stored.
A Letter of Authorization proves to a carrier, datacenter or cloud provider that the holder of IP resources permits a specific network to announce them. Providers typically ask for one before configuring a BGP session, a cross-connect, or a BYOIP onboarding.
An LOA is a statement of permission, not a routing security mechanism: pair it with correct route objects and RPKI ROAs so automated filters accept your announcement too.
