Other Performance Savings
Most organizations will obtain their address blocks from their provider --> they do not need to provide address attestations and do not need certificates
Most DSPs and subscribers use default routing, not BGP --> no need to validate (or receive) attestations
Most organizations/users are singly homed (see above)
Limit where UPDATE validation occurs, e.g., not needed for
- singly homed “leaf” organizations
- singly homed DSPs
- multi-homed DSP -- check only if receive >1 route to same address blocks
