I need help clearing this.
I am listed on dnsbl.spfbl.net
I have run Malwarebytes Premium and Kaspersky. Nothing showed up.

IP: 64.72.42.133
Decimal: 1078471301
Hostname: 64-72-42-133.brhmcmtc01.res.dyn.suddenlink.net
ASN: 19108
ISP: CenturyLink
Organization: Suddenlink Communications
Services: None detected
Type: Broadband
Assignment: Likely Static IP

This is the rDNS found:

<64-72-42-133.brhmcmtc01.res.dyn.suddenlink.net> dynamic or domestic rDNS.
This IP has been flagged because it is dynamic or by suspect to be domestic use only.

If you are running an email service on this IP, ask ISP to change the rDNS.

The removal of this IP from this blacklist depends on change of rDNS to match the FQDN of the mail server.

Are you operating an outbound mail server from that IP address?

I ran the IP through matrix.spfbl.net and it said "This IP has been flagged because it is dynamic or by suspect to be domestic use only."

I believe that it has to do with the/an SPFBL listing, and after some (brief) research, it only really affects mail servers, so unless you are running a mail server from that IP address, you don't really need to worry about it. If you want to be delisted, I believe you can go to https://spfbl.net/en/delist .
