I can't answer for "might", but I did change an entry and had no problems.

For a new entry yes. If there is an existing entry that might have ARP cached with the old address, it could take a bit to update all the ARP
cache entries. IBM i updates by default every 15 minutes. You can
force the ARP cache to clear and have it take effect more quickly.

It's immediate, as easily demonstrated above.

Subject: When does a change to the TCP host table take effect?
I need to modify my host table to:
1) revise an existing entry by changing two host name values
associated this IP address to two new values and;
2 ) add an entry for a new ip address and assign the two original host names previously used in step one to this new ip address.
When does the change take effect? Will I need to bounce TCP ?
