Under my sharing preferences it says: "Other Macintosh users can access your computer at afp://dhcp-183-3..." instead of "Other Macintosh users can access your computer at afp://129.81.183..." if I connect via ssh just using the IP address I get a failed and error for getaddrinfo, authentication, verification. I am within a network that assigns DHCP/IP addresses but it was not until today that this happened and it has not happened on my other computer. I did try to set-up a computer to computer network via airport recently but have that turned off. I also replaced the midplane on my computer this morning but think that is unrelated. Any ideas how to fix this. Am I now some sort of rogue DHCP server on my network?
