They don't have an IPAM built in. IPAMs are usually a back office
thing. It's a deeply personal choice usually made by the very same
monkey in your organization responsible for managing IP allocations.
You can toss IP pool management (in your case, DHCP) at your A10s, but I
don't.
You can also do some interesting things with DNS on the boxes if you
have a software load that supports load balancing. But you don't need
that for NAT. Nor is it wise to put all your eggs into one magical
packet-routing basket.
