What are the advantages/disadvantages of a Dedicated IP address? I currently use a third part firewall and have to whitelist a new IP address frequently. My host offers a dedicated IP address for a fee.
There are some good advantages for sure. So if you are using a shared ip address, and the ip address has a bad reputation, perhaps there are spammy sites using the same ip, it's just not a good thing. Now from my experience, it's not that big of a deal for a website.
What is a big deal is if you are sending email from a shared ip address. It only takes one person sharing that ip to send a bunch of spam email, then the ip gets blacklisted, and now your emails are going to spam until your host can get it removed from the list. That's a real problem had will happen regularly.
