virtual nameservers

Maybe nobody need these informations if not interested in webserver management :)

Virtual nameservers:
I'm pointing my nameservers to the IPs of my webhost's nameservers. So it sounds like 'virtual' is the correct term. Using your example,
ns1.mydomain.com => IP of dnsmyhoster.com's DNS server #1
ns2.mydoman.com => IP of dnsmyhoster.com's DNS server #2

Step 1. Create the nameservers at the registrar (contact your registrar if you dont have direct access).
NS1.mydomain.com => IP#1
NS2.mydomain.com => IP#2

Step 2. Create the nameservers at the host.
It currently looks like this:
example.com. => ns1.dnsmadeeasy.com. (type: NS)
example.com. => ns2.dnsmadeeasy.com. (type: NS)
Should be changed like this:
example.com. => ns1.example.com. (type: NS)
example.com. => ns2.example.com. (type: NS)

Step 3. Add A records on the authoritative DNS servers at the host.
This looks easy enough.
ns1.example.com. => IP#1 (type: A record)
ns2.example.com. => IP#2 (type: A record)

happy hosting
