About MyDNSReport

MyDNSReport is an independent, free DNS lookup and email deliverability toolkit built and maintained by a solo developer. It was created out of frustration with existing DNS tools that were slow, cluttered with ads, or required account registration just to check a domain's records. Every tool on this site — DNS lookup, SMTP testing, RBL blacklist checking, cron validation, subnet calculation — is available to anyone, free of charge, with no login required.

Running this site incurs real costs: server hosting, DNS API bandwidth, domain registration, and ongoing development time. Unlike large platforms backed by investors, MyDNSReport has no funding other than optional user support and non-intrusive affiliate links. Every contribution, big or small, goes directly toward keeping these tools online and improving them.
