# largeicmp

**Explanation**

This Netography event is triggered when an ICMP packet with a large payload is detected on the network. This type of attack is often used to flood a network with a high volume of traffic, causing it to become sluggish or even crash.

**What to Look For**

When examining the results of the largeicmp event, look for the source IP address of the attack and the size of the ICMP payload. This information can be used to narrow down the scope of the attack and identify the systems that are being targeted. Additionally, it's important to look for any patterns in the attack traffic, such as time of day or frequency, as this can help determine whether the attack is being launched from a single source or multiple sources. Once the source of the attack has been identified, network administrators can take measures to block the offending traffic and prevent further damage to the network.
