How many IPs can a dedicated server support?

[AndyB78]

Hello,

Due to a significant (not large but enough to register) number of incidents that affected more customers than the responsible ones we have decided to migrate all customers on dedicated IPs (we are a shared hosting company).

But now we face this question: are the servers going to be able to support such a large number of IPs? Depending on site sizes we host anywhere between 5 to 500 accounts on a dedicated server.

Our servers have roughly these specs:
E3-1230 v3 to E3-1270 v3
16GB of RAM
SSD Intel DC S3500 or DC S3510 in RAID-10 HARDWARE

And of course they all have cPanel with a very small percentage of CloudLinux 6.7 but the vast majority are CentOS 6.7 64 bits.

Are these servers going to support say 500 IPs?

Thanks!

Yes, You can add more then 500 IP's on your server. You should not face any issues with 500 IP's

Thank you! Do you think that it would be good to add more ram? Someone told me that each IP will eat a little bit of RAM.

Hello,

It's difficult to estimate how much RAM is required, but here's a third-party URL that you may find informative:

How much memory is consumed by the Linux kernel per TCP/IP network connection?

Thank you.
