Hi.  We haven't changed our network structure on the IBM I for years and only recently have a need to as all of our processes have been pretty much contained on the I.  I'm self taught in IBM maintenance and learning as I go but I think the changes I need to make are pretty benign but I need some advice.    

I noticed my host table is totally out of whack with my network so I need to remove and correct some entries.  I'm really thinking about only leaving those entries referencing my Virtual IP on the I and otherwise not using a host table.  Ultimately, I need to add some DNS entries and allow external resolution.  Currently my Host name search priority field under CHGTCPDMN is set to *LOCAL.  Is it necessary to change to *REMOTE to make DNS active?  Would this change require an IPL?   If I leave that setting at *LOCAL, Do I need to make a specific entry in my host table or will lookups query my host table and then automatically jump over to DNS for those  queries without a corresponding entry, provided I have the DNS server addresses listed?  
I guess my question(s) are, What is best practice in this case?   Do Host table changes or DNS changes require any service restarts or an IPL or can I just make these changes on the fly?
