Does each email address have its own IP address?

In fact, no email account has an IP address. However, the email servers that pass emails along from send to receiver DO have IP addresses. The IP address you see in the header of your email is the that of the email server that delivered the message to your inbox.

Does same IP address mean same computer?

IP addresses are vital to computing technology, and they come in many different forms… A static IP address remains constant, meaning any device using this form of IP will have the same IP address every time they access the internet or connect with other networks.

Is an IP address specific to a computer?

Essentially, IP addresses are how computers on the internet recognize one another. Your internet service provider (ISP) assigns IP addresses to your internet-connected devices, and every IP address is unique.

Can two computers have the same IP address for private?

Yes. Private IP addresses of two different networks can be same.

Is real IP and public IP same?

Static means the IP address never changes as long as you stay with the same provider or same server. Public means the IP address can be reached via the Internet from any computer in the world. Private means the IP address can only be reached by other devices on the same network.

What happens if you send the same email across multiple IPs?

When an ISP sees that the same message is being sent across multiple IP addresses, it raises a red flag to them that the sender may be a spammer. A basic rule of thumb for good deliverability is to “not look like or act like a spammer.” Use only enough IP addresses to meet the requirements of your mailings.

Why do I have the same IP address on both computers?

Both computers are seen as having the same IP address externally. Your router will relay requests to the originating computer and the procedure used for this is Network address translation. However, if you were to try to communicating with your father’s computer, you would use your internal addresses.

Why do some email addresses have more than one address?

It depends on many factors, including infrastructure, software, and your current deliverability reputation (as many ISPs limit and throttle email based on your sending reputation). Using different IP addresses segmented based on particular mail streams is another legitimate reason for using multiple IP addresses.

How many IPs do I need to deliver 2 million emails?

As an example, say you are sending a campaign to 2 million emails at 8 am, and the campaign needs to be delivered by noon. If it usually takes 12 hours to deliver 2 million emails from one IP address, then to deliver all 2 million emails by noon (4 hours), you would need 2 additional IP addresses (12 divided by 4 = 3 IPs).
