Table 1 lists the differences between 5_bgp, 5_mailbgp, and 5_gray EIPs.

Table 1 Differences between 5_bgp, 5_mailbgp, and 5_gray EIPs

Dimension	5_bgp EIP	5_gray EIP	5_mailbgp EIP
Application scenario	Dynamic BGP provides automatic failover and chooses the optimal path when a network connection fails. 5_bgp EIPs can be bound to cloud resources except dedicated load balancers.	5_gray EIPs are no longer supported.	5_mailbgp EIPs are used together with port 25, 465, or 587 for email services.
Differences	Cannot be used for email services. Can be bound to dedicated and shared load balancers.	Not suggested to be bound to dedicated or shared load balancers by default. Cannot be used for email services.	Cannot be bound to dedicated load balancers. Can be used for email services.
Constraints	The selected EIP type cannot be changed after the EIP is assigned.	In eu-de, existing 5_gray EIPs cannot be bound to dedicated or shared load balancers. You can use 5_bgp EIPs instead. In eu-de, EIPs of the Dedicated Load Balancer (5_gray) type cannot be assigned anymore. You can assign EIPs of the BGP (5_bgp) type.	If you need an EIP of this type, contact the account administrator to grant the required permissions.
