Finding ip addresses from email
There are several factors that come into play when deciding whether to use a dedicated or shared IP with your business. A dedicated IP address is unique to the sender. No other company, organization, or individual can send from that IP address other than your brand. This is a common misconception.
Dedicated IP addresses are not always the answer.
Tracking the location of an IP address
We recommend that senders should only move to a dedicated IP address if:. A shared IP address is shared by multiple senders. For example, say you send your emails through Hubspot without a dedicated IP address.
ESPs understand this and will try to put your brand in an IP pool that is similar to what your emails are about. A big factor depends on the reputation of each IP address. First impressions are everything, and if you make one mistake using a bad link in an email, not following proper IP warming practices, etc. This means if you do something to hurt your reputation with the ISPs, it will take time for them to regain their trust in you as a sender.
This in turn will affect inbox placement and deliverability. From there, you can try to figure out what caused the spam trap hits. Your sending reputation is a critical deciding factor in whether an ISP will deliver the message to the inbox or not. For example, asking AOL to whitelist your dedicated IP address will increase your chances of an approval, versus a sender who has multiple shared IP addresses asking the same thing. You can always be removed based off of your sending practices.

DNS records point right back to your brand. After you figure out the problem, avoid making the same mistakes in the future, as these both have an effect on your deliverability. You are sharing your reputation. Just like the dedicated description, this can be a good or bad thing.

Using this IP address, Active Whois is able to look up additional information such as associated postal and email addresses. We are faced with an additional problem however. Email messages frequently contain more than one 'Received' Headers. How can we know which of these several Headers contains the originating IP address belonging to the sender?

The Sender sends an email message to his own email server to begin its journey to the receiver. A common Headers strings is created. There are other possible variations in email routing. Your Email Service Provider or the provider of the sender may use several 'pass-through' email servers and these servers can add several 'Received' Headers.
Also, if you and the sender use the same server, the message will have only one 'Received' Header. Unfortunately there are those who for various reasons want to conceal their IP address from the message receiver. Most spammers use clever tricks to hide their true IP address.
They can, for example, place fake 'Received' headers into the email headers. They might look something like the following:. In this case, the true sender IP could be in the first 'Received' Header, that is, the one that was inserted by your email service provider's email server, because most spammers send their messages directly to your mailbox without using any intermediate servers.
