Dedicated IP vs Shared IP: Differences, Uses, and Which One to Choose

Shared and datacenter proxies are some of the most popular proxy choices. But a lot of users wonder what actually sets these proxy types apart. While some use cases for dedicated and shared proxies seem similar, in reality, both proxy types operate in somewhat different ways.

This article will lay out everything there is to know about shared and dedicated proxies, how they differ, and explain their key benefits for different needs.

Understanding IP Addresses

Before we jump to proxies, their use cases, and differences, it’s important first to cover some basic ground. For that, we need to look at what defines an IP address, and then explore dedicated and shared IPs.

What Is an IP Address?

An Internet Protocol (IP) address is an identifier assigned to a device that’s connected to the Internet. However, the purpose of an IP address isn’t just to identify a device – it’s essential for overall communication between computers, servers, and smartphones.

It’s like sending a letter – you have to have the necessary contact information for that letter to reach the right person. There are currently 2 IP address versions in use: IPv4 and IPv6. IPv4 is the older IP address type, while IPv6 is a significant upgrade.

What Is a Dedicated IP?

A dedicated IP address is a unique IP address assigned to a single user, website, or server. This type of IP address, or proxy, is assigned to you and your device, so no one else can access it.

The most common use cases associated with dedicated proxies are web hosting, email protection, and accessing applications requiring a single login.

What Is a Shared IP?

In contrast to a dedicated IP address, a shared IP is the complete opposite. Shared IPs are used by multiple users and websites, all at the same time. These proxies analyze each connection request to process incoming and outgoing traffic based on domain names or ports, using DNS records to determine which website or service the traffic should be routed to.

Typically, shared proxies are favored for more day-to-day actions and tasks to reduce costs and boost efficiency. However, while shared proxies are great for everyday users, companies tend to avoid using these proxies due to security concerns.

Dedicated vs Shared IP: Key Differences and Comparisons

Now that we’ve covered some ground about dedicated and shared IP, let’s talk more about their specifics – namely, their main differences and similarities. To better understand what distinguishes shared and dedicated IPs, we’ll go through four key factors and compare them.

• Control and exclusivity: Dedicated IPs belong to one owner only, be it a single user or a company, which gives total control over that IP, its performance, and usage. Conversely, shared IPs are used by many users, resulting in little to no control over IP performance and reputation.
• Security and privacy implications: Shared IP addresses can be considered more anonymous due to the simple fact that a shared IP is used by multiple users, often at the same time, making recognition or traceability extremely difficult. With dedicated IPs, the situation is quite the opposite, providing more security with reduced anonymity.
• Performance and reliability: Dedicated IPs are at a lower risk of getting blocked by websites or apps because they have a single owner only. However, shared IPs circulate through different users, and during peak usage times, performance can drop significantly, leading to slower speeds and unstable connections.
• Cost considerations: Price is often, if not always, the main deciding factor between choosing shared or dedicated proxies. Shared IPs are much cheaper due to the bandwidth being used by many users, lowering maintenance and distribution costs. On the other hand, dedicated proxies bring exclusivity, higher network security, and better connections – all of which drive up the price.

Impact of IP Type on Specific Use Cases

When considering which proxy type to choose, most think about the cost, but you should also carefully think about what you’ll be using the proxies for. Both shared and dedicated proxies have their pros and cons, and benefit unique use cases.

Website Hosting and SEO Effects

If you’re dealing with web hosting providers and are looking for a reliable proxy service, in truth, it doesn’t really matter which proxy type you go with. Both shared and dedicated proxies generally don’t affect search engine rankings.

This is because the systems we have today evaluate websites based on content quality, relevance, user experience, performance, and trust signals. Hosting quality can be a deciding factor, but what really counts is server uptime, page load speed, and security practices.

However, most shared hosting providers support shared IP addresses and have Server Name Indication (SNI), which allows servers to use multiple SSL certificates to add a single SSL certificate to your website regardless of your IP type.

Email Marketing Deliverability

Compared to web hosting, the IP you use does play a rather major role in email marketing. A dedicated IP is crucial in establishing trust as mailbox providers evaluate email behavior, bounce rates, and engagement based almost entirely on the sender’s activity. This means that using a dedicated or shared IP can literally make or break your inbox placement, particularly for high-volume senders.

Shared IP pools can benefit small-scale or infrequent email deliverability, but leaning on shared IPs for multiple emails can lead to negative outcomes like throttling and spam filtering. It’s worth mentioning that you could consider a third-party email provider instead of relying on an IP address for successful email deliverability.

Proxy and Web Scraping Uses

When it comes to web scraping, there’s a bit more to talk about before we can clearly say whether shared or dedicated proxies are better. First things first, dedicated proxies are indeed a common choice because users can lower IP-based blocks, run scraping and automation tasks at higher speeds, and enjoy generally better security.

But this doesn’t mean that shared proxies can’t benefit this use case. Shared IPs are used by smaller teams that have stricter budgets and overall smaller web scraping projects to avoid IP bans and restrictions.

VPN and Secure Remote Access

On a business scale, dedicated IPs give better features and benefits for VPN and remote access use cases. With a fixed IP address, businesses and organizations can control addresses on firewalls, cloud platforms, and internal applications. All of this is essential for proper monitoring processes to maintain security.

Shared IP addresses are mostly used by VPN providers offering services for everyday consumers, prioritizing online anonymity. To all those who could be monitoring connections, it would look like multiple requests are coming from the same IP address, benefiting privacy-first users.

Practical Guidance: When to Choose a Dedicated vs Shared IP

So, now that we’ve gone through the key aspects of IP addresses, covered dedicated IPs vs shared IPs, their differences, and use cases, it all boils down to one question: which one should you choose?

Small Businesses or Beginners

Whether you’re a beginner, a small business, or a startup taking your first steps with proxies, shared proxies are often a good starting place. Shared IP addresses are often more affordable and don’t require complex technical setups, making shared proxies great for websites with low to medium traffic. Moreover, shared proxies also do a great job of handling blogs and small e-commerce stores.

Medium to Large Businesses or Specific Needs

For those operating medium to large enterprises or businesses with specific technical requirements, dedicated proxies are generally a better choice. That’s because dedicated proxies provide high security, performance, speed, and reliable connectivity.

All of these features are necessary for running safety and compliance sessions, implementing advanced firewall rules, and supporting IP-based allowlisting. In short, dedicated proxies provide a single IP address, allowing businesses to take full control over that IP.

Privacy-Conscious Users

Most commonly, users who require high anonymity choose shared IP addresses that rotate the same IP addresses for different users. That alone makes it that much more difficult for external parties to pinpoint a specific user or organization.

At the same time, using the same shared server can come with serious tradeoffs like increased traceability, block rates, network connection instability, and low speeds during high traffic.

Technical Aspects and Advanced Considerations

Once you land with a specific choice, be it shared or dedicated IPs, some additional technical factors can have a real impact on your IP performance. Before we wrap up this article, let’s review some of the most common aspects and go through IP reputation management strategies.

IP Warming: What It Is and Why It Matters

Simply connecting to a dedicated IP address won’t automatically keep you safe from IP flagging, spam filtering, and rate limiting. On the contrary, if you suddenly change your device’s IP address and increase your traffic volume, this will certainly put you on your internet service provider’s (ISP) radar.

That’s where IP warming comes in. It’s a process of gradually increasing email or traffic volume from a new or dedicated IP address to “warm up” to ISPs and receiving servers. This consistency is important for building trust – otherwise, users would be at risk of delivery issues, throttling, or even blacklisting.

IPv4 to IPv6 Transition and Its Effects on IP Usage

While it’s true that IPv4 is still a standard and widely used, the transition to IPv6 has not only begun, but it will be complete in the near future. IPv6 addresses have massive IP pools, allowing users and businesses to get their hands on virtually as many IP addresses as they want, reducing the need for shared IPs.

At the same time, many email providers and legacy systems rely quite heavily on IPv4 reputation models for security and integrity. Because of both IP address versions still being used today, many production environments operate on a dual-stack model, and most proxy service providers support IPv4 and IPv6.

Reputation Management Strategies

Maintaining a strong and trusted IP address requires more than just consistency and awareness – you should also take care to consider all activities when connected to a proxy. Here’s a quick rundown of some of the proven strategies:

• Build traffic consistently and avoid sudden spikes.
• Maintain clean recipient lists and regularly remove inactive addresses.
• Keep tabs on bounce rates, spam complaints, and engagement metrics.
• Separate transactional and marketing traffic across different IPs.
• React quickly to reputation alerts by reducing volume and investigating causes.

Keep in mind that these practices are best suited for managing the reputation of dedicated IPs. Shared IP addresses have many users who can easily influence their reputation, regardless of how well you yourself manage your online activities.

Conclusion

The dedicated IP vs shared IP discussion is more than just a decision of which service is cheaper. It also involves considering your needs and key use cases carefully to land with the right IP address. You can always switch to a different IP type, but knowing the key differences and applications will save you time, effort, resources, and operational headaches in the long run.
