No, DMARC is a protocol that relies only on the configuration of 3 types of DNS records:
1) DMARC record: declares the policy to be applied when validating emails received from your domain. And allows OnDMARC to start monitoring the sources of your email traffic.
2) SPF record: declares the list of IP addresses for the services that are allowed to send emails on behalf of your domain.
3) DKIM records: services sending emails on your behalf should sign these using DKIM and the public key for these signatures are hosted as DNS records.
