I think thats an amazing way to create dns entries for unix servers if you don't access to DNS servers. I believe its possible because of the automatic dns update feature in MS DNS.
Create hostname.txt
server 113.167.14.63
zone ted.com
prereq nxdomain pankaj.ted.com
update add pankaj.ted.com 86400 A 211.216.153.900
show
send
# nsupdate -v /home/scripts/dns/hosts/hostname.txt
You can similarly delete or modify the resource records
# nsupdate
>update delete pankaj.ted.com 86400 A 211.216.153.900
nsupdate is used to submit Dynamic DNS Update requests as defined in
RFC2136 to a name server. This allows resource records to be added or
removed from a zone without manually editing the zone file. A single
update request can contain requests to add or remove more than one
resource record.
