+## Why?
+
+This is a handy script to disable and stop systemd-resolved service.
+
+## How to use?
+
+```bash
+bash -c "$(wget -qLO - https://raw.githubusercontent.com/bigbeartechworld/big-bear-scripts/master/disable-dns-service/disable_dns_service.sh)"
+```
+
+## How to troubleshoot?
+
+Check and see if port 53 is taken:
+
+```bash
+lsof -i :53
+```
+
+OR
+
+```bash
+netstat -tulpn | grep ":53 "
+```
+
+Disable and stop the systemd-resolved service:
+
+```bash
+sudo systemctl disable systemd-resolved.service
+```
+
+```bash
+sudo systemctl stop systemd-resolved.service
+```
