What is the max ping count?

Hey there! As a fellow tech geek and streaming enthusiast, I‘m excited to dive deep into the nitty gritty details on ping counts. I know how frustrating lag and high latency can be when gaming or broadcasting, so let‘s explore what exactly the max ping count means and how it impacts your connectivity.

A Quick Ping Refresher

First, a quick refresher – a ping is a utility that sends a small network packet to a destination and waits for a response. It measures the total round-trip time in milliseconds for the request and reply.

Pings are used to verify basic connectivity and latency to servers or other endpoints. When you ping google.com and see a reply in 15ms, that‘s the total round-trip time it took to reach Google‘s servers and return.

Ping uses the ICMP protocol and sends ICMP Echo packets to the destination. When it gets an ICMP Echo Reply back, it knows the host is up and reachable.

Hop Limits – How Max Pings Work

Now here‘s where max pings come into play. Each ping packet contains a TTL (Time To Live) value that decrements each time it passes through a router. This TTL is also referred to as the hop limit.

For example, a ping with a TTL of 64 would be allowed to traverse 64 hops or routers before being discarded. Each router decrements the TTL by 1 on its way to the destination. Once the TTL hits 0, the packet is dropped and an error is returned.

This prevents ping packets from endlessly bouncing around networks indefinitely. The max TTL or hop limit defines the maximum ping count before expiration.

Common Max Ping Counts

The default TTL values on most operating systems top out between 64-255 hops:

• Windows – Default 128 max TTL, max ping count 128

• Linux/macOS – Default 64 max TTL, max ping count 64

• Cisco IOS – Default 255 max TTL, max ping count 255

So if you ping a Windows server and get "Request timed out" after 128 pings, you‘ve hit the default max! For Linux, that limit would hit after 64 pings.

Here‘s a quick table for common TTL defaults:

Traceroute Reveals the Hop Count

You can use traceroute to see each hop count decrement along the path to the destination. For example:

traceroute to google.com (172.217.18.14), 64 hops max:

 1  192.168.0.1  10ms 
 2  10.20.30.1  12ms
 3  100.90.80.1  15ms 
 4  172.217.18.14  19ms

This shows google.com being reached in 4 router hops from my network. A ping to google.com would timeout after 64 pings thanks to the default TTL limit of 64.

What Happens at Max Ping Count?

Once that TTL field counts down to 0, the final router will discard the packet and return an ICMP "Time Exceeded" message. This means the destination was too far away given the max hop limit configured.

Some examples of the error messages you may see when the max ping count is reached:

• Destination Host Unreachable
• Request Timed Out
• Time Exceeded in Transit

So in summary, the max ping count defines when the TTL hop limit expires, causing routers to drop the ping packet. It prevents endless packet looping on network failures.

Increasing the Max Ping Count

In some cases, you may want to increase the max ping count TTL for troubleshooting purposes. Here are a couple examples:

• Testing packet handling over a complex topology with many hops
• Verifying connectivity to distant servers across the public Internet
• Debugging packet loss patterns across high-latency links

On Windows, the maximum TTL allowed is 255, so you could increase from the default of 128 up to 255 to test wider network paths.

However, I‘d recommend keeping it temporary, as high TTLs and ping counts can bombard routers with unnecessary traffic. Use wisely my friend!

Key Takeaways

Hopefully this gives you a better idea of how max ping counts operate behind the scenes! Here are some key takeaways:

• Max ping count is dictated by the TTL (Time to Live) field in the ping packet header
• Each router decrements the TTL by 1, discarding the packet once it reaches 0
• Default max TTL values range from 64-128 on most OSes
• You can increase the max ping count up to 255 for specialized testing
• Reaching the max ping limit returns "destination unreachable" errors
