Static/Dedicated IP addresses allow for a certain amount of anonymity. It makes the reseller look more indendant of a host.
As Alex mentioned they are also necessary if you plan to have a SSL certificate installed on your site.
What are Static IP Addresses used for in reselling? Are they important for the customers?
MMhosting.com offers them in their reseller plans but I don't know anything of their functionality.
Thanks.
How so? The IP netblock owner is still belongs to the hosting company, not the reseller since the IP address can't be re-delegated (SWIP) to the reseller.
There really isn't any anonymity to assigning an IP address since anyone with a dnsstuff.com account or even SSH shell account can run a WHOIS on the IP address and quickly determine the parent company.
Of course, the hosting company can take measures to change the IP block ownership to something other than their name but it still doesn't belong to the reseller.
SSL requrties to have dedicated IP. So that is why IP is being usally ordered
Those sending mail from their domain name will benefit from a dedicated IP. A shared IP can easily be blacklisted for sending spam if just one of the clients sharing it sends something spammy.
On a dedicated IP you don't have to worry about someone else's mistake resulting in *your* email being rejected.
Yes, it is definitely possible that your Dedicated IP's will get Blacklisted. However, IP's get Blacklisted if you use them for Illegal activities or some other activities which are not allowed. Hence, it is suggested that you should use the IP's for genuine reasons and make correct use of those IP's.
This doesn't mean you are the one who got them blacklisted in the first place. As Steve said, it's a real pain to get them unlisted. I don't even bother trying.. Next IP please!
