moderator plz transfer this topic if not in appropriate section

hello all,

i have 2 static ip and i am going to configure them to one my subdomain ... i would like to know that

if i assign

1.1.1.1 --> my.mysubdomain.com
2.2.2.2 --> my.mysubdomain.com

if my 1.1.1.1 is not in use will it resolve automatically to
2.2.2.2 and vice versa

Thanks
