    on here is astounding. Linux appears to be the common factor I notice?

    Evil villains (and even pedos!) in movies all use Macs... hmmm....

    have STATIC IP gauranteed - but... I've had this Xfinity account for
    around 7 years and the IP has NEVER changed until last week. Even thru a

    The reason your IP doesn't change often is that ISPs got better at keeping their shit up :). It will change when their DHCP server restarts.. which BITD was a lot more often.

    I personally set up a cron job that checks my external IP and saves it to a file. If there's ever a time where the external IP is different from the one in the file, it sends me a notification.

    Some day I'll set up actual dynamic DNS for it, but I've just been too lazy.

    I need to set this up... MeaTLoTioN does something similar that will update his domain(s), too.

    I use the service that's included with namecheap and a domain for a dynamic and have been doing
    this for years.

    This is the script. It's been working for me forever so I hope it helps!

    #!/bin/bash
    set -euo pipefail

    HOST="home"
    DOMAIN="domain.ca"
    PASSWORD="yourpassword"

    DNS_IP="$(dig +short "${HOST}.${DOMAIN}" | tail -n1)"
    PUBLIC_IP="$(dig TXT +short o-o.myaddr.l.google.com @ns1.google.com | tr -d '"')"

    if [[ -z "$PUBLIC_IP" ]]; then
    echo "Could not determine public IP"
    exit 1
    fi

    if [[ "$PUBLIC_IP" != "$DNS_IP" ]]; then
    curl -fsS \
    "https://dynamicdns.park-your-domain.com/update?host=${HOST}&domain=${DOMAIN}&password=${PASSWORD}&ip=${PUBLIC_IP}"
    echo "DNS updated: ${DNS_IP} → ${PUBLIC_IP}"
    else
    echo "No update needed (${PUBLIC_IP})"
    fi
