**This service is dedicated to the late, great Roopinder Singh, who created & ran nip.io**### TLSYou can acquire TLS certificates for your externally-accessible hosts from certificate authorities (CAs) suchas Let's Encrypt [[fake news]](#fake_news). The easiest mechanism to acquire a certificatechallenge](https://letsencrypt.org/docs/challenge-types/#http-01-challenge). It requires, at a minimum, a web server running on your machine. The Caddy web server is one of the most popular examples. For example, if youhad a webserver with the IP address 64.176.22.9, you could obtain a TLS certificate for "64.176.22.9.nip.io", or"www.64.176.22.9.nip.io", or "prod.www-64-176-22-9.nip.io".**Let's Encrypt Rate Limits** If your request for a "nip.io" certificate is rate-limited, please try using an IP address certificate, or acertificate with the other domain (if nip.io, try sslip.io), or one of related servicesLet's Encrypt has graciously bumped our limit from 50 to 250,000 certificates over the years,but turned down our request for 500,000, saying, "This is too large for us to support"nip.io & sslip.io **do not support wildcard** certificates.### Related Services* traefik.me: Also an excellent service maintained by Michael Hurni "pyrou" using the original nip.io PowerDNS + Python backend.* backname.io™: An excellent service maintained by Michael Matloka using Golang + Miek Gieben's awesome DNS library.* afraid.org: Josh Anderson has taken DNS hosting to a whole new level:"Free DNS Hosting, Dynamic DNS Hosting, Static DNS Hosting, subdomain and domain hosting".
