how can i identify traffic that goes to the kinesis video service

Question

I'm trying to do some traffic shaping so an offline upload of a file doesn't flood my network connection.
But to create these tc rules i need to know either the destination ip address and/or the ports that are used for uploading.

Is there a default port that gets used ? I noticed the kinesis video end-point is a dns ( http://kinesisvideo.ap-southeast-2.amazonaws.com/ ) , and apparently it can resolve to multiple ip addresses.. so i'm just wondering what would be the best way to identify kvssink -> kinesis video traffic

from a network capture I think i can see that it goes to port 443, but i can't just filter on that because every connection to https is using that port.

if i lookup in  https://ip-ranges.amazonaws.com/ip-ranges.json

it doesn't seem to have any entry for 
      
```
       "region": "ap-southeast-2",
```
and
```
       service": "KINESIS_VIDEO_STREAMS
```
any idea on how i can identify traffic to kinesis video ?

Answer

maybe i'll just do a ping every now and again and then look it in the cache 
```
ping -c 1 -W 1 kinesisvideo.ap-southeast-2.amazonaws.com > /dev/null; sudo killall -USR1 systemd-resolved ; sudo journalctl -u systemd-resolved > ~/dns-cache.txt ; cat ~/dns-cache.txt | grep "kinesisvideo.ap-southeast-2.amazonaws.com" | grep "IN A " | grep -v NXDOMAIN | tail -n 1 | rev | cut -d ' ' -f 1 | rev

3.104.149.251
```

or directly at the ping output

```
ping -c 1 -W 1 kinesisvideo.ap-southeast-2.amazonaws.com | head -n 1 | cut -d '(' -f 2 | cut -d ')' -f 1
3.104.149.251
```

Answer

Those IPs are subject to change.  it is a good idea that as you already did to get the most recent IP addresses using the scripts you shared.

Answer

Hello

Because of load balancing, the IP are changing when resolve kinesisvideo.ap-southeast-2.amazonaws.com.

I did  a quick test to resolve the kinesisvideo.ap-southeast-2.amazonaws.com, even it is changing, but it will in the following IP addresses:

3.104.149.251
13.236.240.54
13.236.62.73

so you can filter above three IP addresses only . 
Hope that helps, if not, please don't hesitate to reply.

Regards!
