Self-hosted blog - do I need a static IP address? (lemmy.ml)

hi everyone,

I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.

Is that true?

(I'd not seen much about that in stuff I've looked up so far about self hosting)

Cloudflare is a good choice. I used DNSExit for a while, and also NS1, but settled on Cloudflare. You don't have to use their proxying, just DNS.

Here's a Docker Compose for you that will set myhost.mydomain.com to point to your public IP of wherever it is run:

dyndns-cloudflare:
    image: oznu/cloudflare-ddns
    container_name: dyndns-cloudflare
    environment:
      - API_KEY=<key>
      - ZONE=mydomain.com
      - SUBDOMAIN=myhost
      - PROXIED=false
    restart: unless-stopped
