Questions in regards to Domain and port 80 being blocked

[alden.pierre]

I have a few questions in requards to registering a domain.

1.  My ISP blocks port 80 is there a work around which will allow me to 
run my own web server?

2.  My IP is dynamic will this effect me if I want to run my own email, 
ftp, or web server?

3.  Since my IP is dynamic is there a specific domain register I should 
be looking into?


Thank You
