Do you regularly ssh into machines which have dynamic IP addresses, and get really annoyed with OpenSSH warning that the IP's key doesn't match the host key? I certainly do, with machines announce their names using mDNS and a DHCP server in my router. Today I finally checked the documentation and found out how to skip this check.

The magic option is CheckHostIP, which you can set in .ssh/config on a per-host level. I've got this in my config: 

Host *.local
  CheckHostIP no

Now all machines I ssh into using a .local domain won't have their IP's key checked against the host key, because the IP is dynamic. Sorted!
