Abdulhadi,
Honestly, I think that a design spec of getting DNS responses in 3ms across the board is unrealistic. My initial MX query for litc.ly took 367ms:
;; ADDITIONAL SECTION:
exmail.litc.ly. 14400 IN A 197.215.159.227
dns2.lttnet.net. 21600 IN A 62.240.36.40
dns3.lttnet.net. 21600 IN A 62.240.36.40
;; Query time: 367 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Sun Jul 9 12:50:58 2017
;; MSG SIZE rcvd: 144
Additionally, given the operational environment in which you exist I would recommend that you strive for just providing good DNS services in general.
Good luck.
John

HI,
we are ISP company , we are providing Internet to our customer, Recently one of our VIP customer ask for DNS service, and need the response time 3msec, we don't have enough knowledge of DNS,
1- To achieve the goal of my customer about the response time I need to know what's the optimal design solution for DNS ( Authoritative or Recursive(,or there is other design.
2- If the answer in the previous question an "authoritative", is there any registration & technical requirements for so (i.e. ccTLD, ... )
Best regards
