Frequently Asked Questions

How does SledgeSPF prevent lookup limits?

We query and expand all dynamic includes into direct IPv4 and IPv6 blocks, serving flat TXT records at the edge so your domain never breaches the RFC 7208 10-lookup threshold.

What is dangling CNAME takeover detection?

When you decommission a cloud host without removing the CNAME record, attackers can register that bucket/endpoint and hijack your subdomain. Sledgeheader flags dangling pointers immediately.
