### How to Define a <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> Record

---

<abbr class="glossary" title="Sender Policy Framework">SPF</abbr> means "[Sender Policy Framework](https://en.wikipedia.org/wiki/Sender_Policy_Framework "SPF records")", and can be used to avoid forging of sender's addresses in emails. It is not a record type of its own, but uses **TXT** records for this.

**There should always be only one <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> policy record** for a domain, while the <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> definition may contain several different rules, and can be split over multiple TXT records with different names, if needed.

There are many tools online available to help with creating a <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> record for a specific domain, e.g. [this one](https://www.spf-record.com/generator "SPF generator").

For instance, your Joker.com-domain is "example.com", and you want to allow emails from Gmail, you have to create a <abbr class="glossary" title="Domain Name Server">DNS</abbr> record of type "TXT" for your domain "example.com", and enter this line:

```
v=spf1 include:_spf.google.com ~all
```

In case you want to make use of a <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> record for a Joker.com domain, and want to make sure that emails from Joker.com will reach email addresses using your Joker.com domain, you need to add (include) this additional rule to your <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> policy:

```
include:_spf.joker.com
```

resulting in this <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> policy:

```
v=spf1 include:_spf.google.com include:_spf.joker.com ~all
```

You can create more than one TXT record to split the <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> policy rules, then the records should all start with <span style="color: rgb(0, 0, 0); font-family: monospace, monospace; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.08px; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: rgb(236, 240, 241);">v=spf1</span> to define one <abbr class="glossary" title="Sender Policy Framework">SPF</abbr> policy and every record must have a different name, or in other words - for every unique name (including domain itself) only one record starting with <span style="background-color: rgb(236, 240, 241);"><span style="color: rgb(0, 0, 0); font-family: monospace, monospace; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.08px; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: rgb(236, 240, 241);">v=spf1</span></span> is allowed:

### <abbr class="glossary" title="Domain Name Server">DNS</abbr> PTR Records

---

A <abbr class="glossary" title="Domain Name Server">DNS</abbr> pointer record (PTR for short) provides the domain name associated with an IP address.

A <abbr class="glossary" title="Domain Name Server">DNS</abbr> PTR record is **exactly the opposite** of the A-record, which provides the IP address associated with a domain name.

<abbr class="glossary" title="Domain Name Server">DNS</abbr> PTR records are used in [reverse <abbr class="glossary" title="Domain Name Server">DNS</abbr> lookups](https://simple.wikipedia.org/wiki/Reverse_DNS_lookup). When a user attempts to reach a domain name in their browser, a <abbr class="glossary" title="Domain Name Server">DNS</abbr> lookup occurs, matching the domain name to the IP address.

A reverse <abbr class="glossary" title="Domain Name Server">DNS</abbr> lookup is the opposite of this - **it searches for a domain name with the given IP address**.

This also means that **PTR records can not be defined using the name servers of the domain, but have to be requested at the provider of the IP address**, in case the provider supports this.
