I'm late to the party, but this article inspired me to write this script to slow down connections to reddit
#!/usr/bin/env bash
DEV=enxe04f439470d2
DOMAIN=reddit.com
LATENCY=5200ms
sudo tc qdisc del dev $DEV root # Ensure you start from a clean slate
sudo tc qdisc add dev $DEV root handle 1: prio
sudo tc qdisc add dev $DEV parent 1:3 handle 30: netem delay $LATENCY
for IPADDR in $(dig @8.8.8.8 +nocmd $DOMAIN any +multiline +noall +answer | grep -E -o "([0-9]{1,3}[\.]){3}[0-9]{1,3}")
do
echo "Slowing down connections to $IPADDR on $DEV"
sudo tc filter add dev $DEV protocol ip parent 1:0 prio 3 u32 match ip dst $IPADDR flowid 1:3
done
