[dns-operations] Akamai now works with ENT (Empty Non-Terminals)?

[Jared Mauch]

Yes. I know Tale spent a long time working on this and I believe all the software went live recently on this. If you are seeing issues let me know and I can pass it on to the team. 

This should mean good things as it makes QNAME minimization feasible where it was not previously. 

(I forget it may have gone live last year)..

If anyone needs an exact timeline I can go find it.
