excellent, it is possible to create a dhcp server with more than 20,000 ips on an aws server

Glad you liked the video. Yes, it is possible to create DHCP server with more than 20,000 IPs, however there isn't a managed service available which can be used directly. To handle such a large number of IP addresses, you need to select an EC2 instance with sufficient resources, like CPU, network performance, memory etc. The excat instance type required would depend on the expected workload and the number of DHCP client expected to be served simultaneously. The VPC and subnet CIDRs should also be sized accordingly to accomodate the required number of IP addresses. I hope this answers your question.
