What are IP Addresses?
When you submit posts to Reddit on your computer or mobile device Reddit sees your post as coming from a specific IP address. This is like a home address; your home address identifies your physical location in the world, and an IP address identifies your device's location on the Internet.
Like a home address, your IP address can change over time. You can even hide your IP address from the outside world by tunneling your Internet traffic through a VPN (virtual private network). Websites will receive the IP address of the VPN device rather than your device.
IP addresses comes in a format like 192.158.1.38

How Postpone Handles IPs
Postpone submits all Reddit posts, comments, and direct messages from our servers. When submitting your content, we proxy traffic through a pool of servers which each have their own IP addresses. Postpone has access to over 7 million IP addresses. Each submission picks a new, random IP address. The proxy servers are all located in the U.S.
Here's a representation of how submitting a post from Postpone is proxied through servers before going over the Internet. Reddit then sees the IP address of the proxy server:
Submitting posts through IP proxies helps ensure that your posts are not rate limited due to IP address, which protects your account.
