Wrong SPF record for zoho.com and zcsend.net domains

Wrong SPF record for zoho.com and zcsend.net domains

Hi, I'm an email server administrator.
Checking logs on my email server (a script automatically update, parsing spf records of well know senders, a whitelist to avoid "false positive") I noticed that there is a wrong entry in the spf record of zoho.com and zcsend.net domain:

2607:13c0:0002::1000/115 (is formally wrong, this generate a parsing error, maybe it's a typo error)

should be:
2607:13c0:0002::1000/116 (network range: 2607:13c0:0002::1000 - 2607:13c0:0002::1fff)
