Due to the global shortage of IPv4 addresses, although there is no limit on the number you may have, we are now required to request justification for dedicated IP address requests.
The only acceptable justification for a dedicated IP address on any account type that we can accept at this time is for use with an SSL certificate.
Shared Hosting Plans
You can only have one (1) dedicated IP address per Shared account. The dedicated IP address must be assigned to your entire cPanel. Your primary domain and all addon domains and subdomains will use the same IP address. You cannot purchase a dedicated IP for only an addon domain. However, an SSL certificate can be for any domain name on your account, including addon domains.
