How to set host table?

[Takanobu Kawabe]

Hello, my name is Takanobu Kawabe.

I use MySQL 4.1.19 server now.
I  don't know  how to  set  Host  table  in mysql  database.

For db table,tables_priv  table and so on, can set  using  GRANT SQL 
statement.

Can I  use  this statement  for  setting  Host  table?

If  I can, what  SQL statement can I use?

Otherwise,  can I only  insert  the host  table  depended on db table?
