Ethereum mining remains a compelling way for individuals to participate in blockchain networks and earn cryptocurrency rewards. One of the most recognized platforms for this purpose has been Poolin, a major mining pool that once supported Ethereum (ETH) mining. While the Ethereum network has transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS), many miners still seek updated information on mining pool connectivity—especially regarding IP addresses—for legacy systems, alternative blockchains, or educational purposes.
This guide explores how to locate current and reliable IP address configurations for Ethereum-related mining operations, with a focus on best practices, trusted sources, and network stability. Whether you're managing existing hardware or exploring decentralized computing, understanding how to maintain proper pool connections is essential.
Understanding Ethereum Mining Pools
A mining pool is a collaborative network of miners who combine their computational power to increase the likelihood of solving complex cryptographic puzzles and earning block rewards. Once a block is successfully mined, the reward is distributed among participants based on their contributed hashrate.
Before the Ethereum Merge in 2022, mining pools like Poolin played a vital role in securing the network under the PoW consensus mechanism. Although Ethereum no longer supports mining, some forks—such as Ethereum Fair or EthereumPoW—still operate using PoW, keeping demand alive for functional mining configurations.

Why Do Mining Pool IP Addresses Change?
It’s common for mining pools to update their server IP addresses periodically. Several factors contribute to these changes:
- Server Maintenance & Upgrades: To improve performance and uptime, pools may migrate to new data centers or cloud infrastructures.
- DDoS Protection: Frequent IP rotation helps mitigate distributed denial-of-service attacks, which are common in high-value crypto networks.
- Geographic Optimization: Some pools deploy region-specific servers to reduce latency and improve connection stability.
- Security Enhancements: Changing IPs limits long-term exposure to malicious actors scanning for active mining nodes.
As a result, relying on outdated IP addresses can lead to connection failures, rejected shares, and lost revenue—even on active PoW chains.
How to Find Updated Mining Pool Server Addresses
To ensure continuous and efficient mining operations, it's crucial to use accurate and up-to-date server endpoints. Here are the most reliable methods:
1. Official Website Resources
Always start with the official website of the mining service. For Poolin and similar platforms, visit the Mining Pool section and navigate to the server configuration or connection guide page. These sections typically list:
- Primary and backup IP addresses
- Port numbers for stratum connections
- Regional server options (e.g., Asia, North America, Europe)
Ensure you’re accessing the legitimate domain to avoid phishing scams.
2. Social Media & Announcements
Mining pools often publish real-time updates via:
- Twitter/X posts
- Telegram channels
- Discord announcements
Following verified accounts ensures you receive immediate alerts about IP changes, maintenance windows, or security advisories.
3. Community Forums and Discussion Boards
Engaging with communities such as:
- Reddit’s r/EtherMining
- Bitcointalk.org threads
- Mining-focused Discord servers
…can provide peer-verified insights into working IPs and troubleshooting tips when connections fail.

Best Practices for Stable Mining Connections
To maximize efficiency and minimize downtime, consider the following strategies:
Use Multiple Server Endpoints
Configure your mining software (e.g., GMiner, T-Rex, or PhoenixMiner) with at least two server addresses:
- A primary server
- One or more fallbacks
This setup allows automatic failover if the main node becomes unreachable.
Monitor Latency and Rejection Rates
Regularly check your miner logs for:
- High ping times (>100ms)
- Frequent "connection timed out" errors
- Share rejection due to stale submissions
Adjust your server selection if performance degrades.
Keep Software Updated
Use the latest version of your mining client to benefit from:
- Improved stratum protocol support
- Bug fixes
- Better error reporting
Outdated miners may fail to connect even with correct IPs.
Frequently Asked Questions (FAQ)
Q: Is Ethereum still mineable in 2025?
A: No. Ethereum completed its transition to Proof-of-Stake in 2022. However, some forks like ETHW (EthereumPoW) remain mineable using GPU or ASIC rigs.
Q: Can I use old Poolin IP addresses for current mining?
A: Not reliably. IPs change frequently for security and performance reasons. Always verify through official channels before configuring your rig.
Q: What ports are typically used for Ethereum mining pools?
A: Common ports include 3333, 8008, 8888, and 4444. The exact port depends on the pool and protocol (Stratum V1 or V2). Check your pool’s documentation.
Q: How do I test if an IP address is active?
A: Use command-line tools like ping or telnet:
telnet us-east.ethw.poolin.com 3333If the connection succeeds, the server is reachable.
Q: Are there risks in using third-party IP lists?
A: Yes. Unofficial sources may provide hijacked or malicious endpoints designed to steal hash power or credentials. Stick to verified platforms only.
Q: What happens if my miner connects to an outdated IP?
A: You’ll likely see “connection refused” or “unable to resolve host” errors. Your rig won’t submit shares, resulting in zero earnings.
Staying Informed in a Changing Landscape
While traditional ETH mining is no longer viable on the mainnet, the knowledge and infrastructure developed during the PoW era remain valuable. Many miners have transitioned to other cryptocurrencies such as Ravencoin, Kaspa, or Zcash—all of which support GPU-based mining.
Moreover, understanding how to manage pool configurations, monitor network health, and adapt to infrastructure changes builds long-term resilience in the crypto space.

Final Thoughts
Although Ethereum has moved beyond mining, staying informed about mining pool configurations—including up-to-date IP addresses—remains important for those involved in alternative PoW ecosystems. By relying on official sources, engaging with trusted communities, and maintaining flexible setups, miners can continue to operate efficiently in an evolving landscape.
Whether you're revisiting legacy systems or exploring new opportunities in decentralized networks, accuracy and adaptability are key. Always verify server details before deployment and stay alert for updates that could impact your operations.
