Will my idea work?

I need to change the ndpsm load command in my cluster from

load ndpsm ".NDPSMK.ou" /DBVOLUME=NOCHECK /IPADDRESS=10.0.0.2

to

load ndpsm ".NDPSMK.ou" /DBVOLUME=NOCHECK /DNSNAME=prnt.domain.int

so I thought I would change the load command to

load ndpsm ".NDPSMK.ou" /DBVOLUME=NOCHECK /DNSNAME=prnt.domain.int
/IPADDRESS=10.0.0.2

so the questions

1. can I add the /DNSNAME and /IPADDRESS at the same time to the load
script?
2. will the printers when given a DNS name install using that or still
use the IP
3. Will it affect the currently installed printers that point to the
ipaddress instaed of the dns name?

I am running a netware 6. sp7 5 node cluster
