Hi! I'm Ruurtjan Pul, a full-stack developer who used to suck at DNS. I've had many side projects over the years, and never completely understood why my DNS records didn't update. Or how long to wait until they do. Worse yet, I've had my emails bounce because I misconfigured SPF, DKIM and DMARC. I decided to learn DNS by making Wirewiki.com, a web interface for internet infrastructure data, including DNS. I've read the RFCs to implement a custom DNS client and I now run my own DNS server. https://www.wirewiki.com
