This does not sound very critical.
What can an attacker do with an eclipse attack? It allows the attacker to launch a 51 percent attack with 40 percent mining power. Suppose the network contains 3 large mining nodes. Two control 30 percent of the mining power, and one controls 40 percent. If the attack owns the 40 percent mining power node, it can partition the other 2 miners so that they cannot build off of each other’s blocks, and can outcompete each partitioned miner. As a result, the attacker’s blockchain becomes the consensus block chain. Another attack is the n-confirmation double spending attack. This attack is more complex and is described in more detail in the paper.

The attack requires the users’ nodes to restart. However, this occurs fairly frequently because of software updates, packets of death/DoS attacks, and power/network failures.
How ofter do miners nodes get taken down?
How many nodes do big mining pools have? Are they limited to a single node? How do you know their ipv4 connection is the only one?
