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)
The first link in my previous comment is literally gmail returning an error because no ptr…
Edit: your page is about setting up dkim while using their workspaces. You don’t control their ptrs.
Edit2: notice they don’t talk about SPF or dmarc on that page either. SPF has been require for google as well for a while and dmarc is highly recommended though not strictly required.
From over a year ago. Requirements change.
Your page is explicitly a support page for dkim config. It is not a list of email requirements. YOU don’t control their ptr records. Ptr records are placed on the IP space side. Google controls theirs for workspaces. So that page won’t have help on the matter. Requirements haven’t changed. I control systems that send millions of messages a month…
Ptr, SPF and dkim are now mandated. Dmarc is highly recommended for gmail…

How many links you need before you recognize that you’re wrong? All three of these are from last 10 months. One of which was from March.
I don’t know what to tell you. I’m literally looking at my DNS records at cloudflare that point to my home IP and there is no PTR entry and yet I have dozens of emails in my gmail account about scheduled process and Prometheus alerts etc. The last undeliveryable I got from Gmail was 2 month ago when I was setting up the email server. Maybe because I’m on Google Fiber it’s not enforcing it but I have no PTR record.
PTR records are NOT on the domain side.

An example record lookup would be
8.8.8.8.in-addr.arpa. Like I’ve said twice now. YOU don’t control google’s PTRs (since you linked to google workspaces). They DO have PTRs setups.IP of 142.251.2.109 resolved for my DNS.
https://easydmarc.com/tools/ptr-record-lookup?domain=142.251.2.109&dns_server=1.1.1.1&dns_type=PTR
Resolves to a record name of
dl-in-f109.1e100.netEdit: Another name for a PTR record is rDNS. Or Reverse DNS. and that name is a bit more descriptive in that it’s IP -> Name rather than DNSes normal job of Name -> IP address
I don’t use Google Workspaces that’s just the first article I found.
Maybe I misunderstood then. I though PTR records had to resolve to your email domain, not just match the IP address with an A record that resolves to the same IP. There is a PTR record that resolves to ip.googlefiber.net but it does not match my email domain.
PTR requirements are generally that it “resolves”, not that it explicitly needs to match anything (Which I never understood as a choice). But PTR records are set by the IP address owner/holder. If you’re saying that you have google fiber, then Google would have control over the PTR and you’d have to ask them to set it (if they do…).
If you dump your IP into the easydmarc tool in my previous comment or any other tool that resolves PTR, you’ll likely find that it resolves to something.
Or you can drill or nslookup the record as well (
drill -x <ipaddress>ornslookup <ip address>I believe).
