[Mailman-Users] Beginner questions

[António P.F.Ferreira de Almeida]

I' m very new to Mailman and would like to ask a few questions :
1. For creating a small mailing list (200/300 members), using Mailman and Apache, in a home computer running Linux, can I use a dynamic IP or do I need a fixed IP ?
2. How do I assign that IP (fixed or dynamic) to an existing domain ?
 
Thanks
