# Merging SPF records

On some rare instances, users may require an extensive list of SPF Records for their Emails and discover the 255-character limitation in place.

To bypass this limitation and increase the amount of records that can exist against a domain is to merge multiple records together using the **"include"** feature of the SPF ruleset.

The example below is of an existing record that needs to be modified for a list of IPs.

```plaintext
example.com.au. TXT "v=spf1 +a +mx +ip4:221.121.129.3 -all"
```

We will need to create a new TXT Record in our DNS Zones like so:

```plaintext
_spf1 TXT "v=spf1 +ip4:221.121.129.2 +ip4:221.121.134.34 include:m.google.com ~all"
```

Once the new record is created, we can modify the original record and use our new TXT Record above as an **‘include’** *(noted as include:_spf1.example.com.au)*

```plaintext
example.com.au. TXT "v=spf1 +a +mx +ip4:221.121.129.3 include:_spf1.example.com.au -all"
```

After this DNS change has been made and has propagated successfully, the SPF records will now include both sets of rules.
