We are starting to look at CGNAT solutions. The primary motivation at the moment is to extend current IPv4 resources, 
but IPv6 migration is also a factor.

IPv6 Migration is generally not aided by CGNAT.

In general, the economics today still work out to make purchasing or leasing addresses more favorable than CGNAT.

It’s a bit dated by now, but still very relevant, see Lee Howard’s excellent research presented at the 2012 Rocky
mountain v6 task force meeting:

We've been in touch with A10. Just wondering if there are some alternative vendors that anyone would recommend. We'd 
probably be looking at a solution to support 5k to 15k customers and bandwidth up to around 30-40 gig as a starting 
point. A solution that is as transparent to user experience as possible is a priority.

Thanks
