Binary dns_sesame is a DNS server responding desired IP addresses.
It is useful against firewalls wanting a fixed set of domains and opening only on the IPs resolved.
go run dns_sesame.go -address :53 -suffix z.stalkr.net
How it works: - choose a name ('test'), send a DNS request to set the IP
e.g. dig 126.96.36.199.test.z.stalkr.net >/dev/null
- request that name, it will have the desired IP
e.g. dig +short test.z.stalkr.net => 188.8.131.52
Response TTL is 300 (5 minutes). Pick a random name to avoid colliding with others. Use multiple names to pool responses until TTL expires.
