You change the NS RRset in the zone then inform the parent
of the changes. Note you should not try to change all the
NS records at once.
Depending apon the zone and where it is in the heirarchy you
will need to take to different people. Assuming the zone is
immediately below a infrastucture zone.
* For a forward zone then you need to talk to the registrar for
the zone (in your case networksolutions).
* For the reverse zone you need to talk to the RIR (in your case
ARIN).
If it is not immediately below a infrastucture zone then you should
be able to strip the lefthand label and query for the SOA record
using the resulting name. This will normally return the parents
SOA record either in the answer section or in the authority section
when there is multiple levels in the parent zone. Note some older
nameservers may not return the SOA in the later case so you strip
another label and repeat.
Once you have the SOA record the second field should have the
email address of whom to contact at the parent.
