If you want to use Links with an apex/root URL (lyrdy.co instead of link.lyrdy.co) you will have to do some things differently.
If your provider supports apex/root records (Cloudflare, AWS Route53, DNSimple, IBM NS1, etc), you simply have to create an ALIAS record (or CNAME on Cloudflare) for @ that goes to cname.layeredy.com
If your provider does not support apex/root records, you have to create an A record that directs to 144.217.167.146 (IPv6: 2607:5300:205:200::7446). (Note: If our IP changes, you will have to go in and modify this record. You will be emailed if this IP changes)
