# nip.io / sslip.io

**Canonical:** https://apis.io/providers/nipio/  
**Website:** https://nip.io/  
**APIs profiled:** 0

nip.io and sslip.io are a single wildcard-DNS service that resolves any hostname containing an embedded IP address to that address — 93-184-216-34.nip.io and 93.184.216.34.sslip.io both return 93.184.216.34, with no signup, no configuration and no records to create. It exists so developers can put a real hostname in front of an arbitrary IP for local development, TLS testing, Kubernetes ingress and CI, and it has been in operation for over ten years. The operators state the service answers more than 20,000 queries per second. The DNS server behind it is open source: cunnie/sslip.io, written in Go and licensed Apache-2.0.
