[web2py] Auto populate form

[Saba]

hello,
 
I have a table like this:
 
db.define_table('host',
    Field('host_name', requires=IS_NOT_EMPTY()),
    Field('host_ip', requires=IS_NOT_EMPTY())
)

i'm using SQLFORM.grid to display/edit the data in the table. When a user 
inputs a host_name field, I would like to automatically populate the 
host_ip field by doing an nslookup of the host_name. Is there a way to do 
this. Any suggestions please?
 
thanks,
Saba
