It's ns2.todhunter.com
the soa has mname field as ns2.todhunter.com, but that field is manually edited (errors), and not a technical proof that the primary is ns2 and all the others are slaves.
You can't say definitively which NS is the master and which is slave by querying only. There is no DNS query that says "which NS is the master, which is slave?".
One practical indication, but not proof, that all is well with master/slave replication is that if all the NS's have the same zone serial number. This is the case with todhunter.com. I would say NetSol doesn't know what they are talking about.
The only definite way to know if an NS is master for a zone is to look at the zone config on each NS to see if the NS is declared master or slave for the zone.
ns2.todhunter.com has security vulnerability with unrestricted zone transfers:

Another error is that public zone is publishing private IP addresses. There should be a separate zone for the private IP space.
