Skill issue. Works fine for me in a mixed Linux/Apple environment.

I didn't write any mDNS software. Blame those guys.

[guntars]

Well I mean “those guys” did a good job and the network administrator might need to do some debugging.

[zadikian]

I never have to debug why my dhcp server isn't handing out ipv4 addresses or deal with conflicts, but if I did, it'd break mdns too. mdns is an extra moving part to deal with.

[guntars]

By debugging I mean just checking if you have not blocked broadcast packets at the firewall or some similar misconfiguration. I doubt it’s actual bugs when it doesn’t work. On your second point, it’s actually more resilient than DHCP because it works with IPv6 too.

[zadikian]

Idk, just checked my LAN-connected Mac's arp tables now and none of the hostnames are there, even after I ping the multicast. Haven't messed with any settings.

[guntars]

Does anything respond to the multicast ping? If that doesn’t work then mDNS isn’t going to either. Router config is the likely culprit.

[vel0city]

I've had numerous issues with dhcp servers over the years and clients not understanding their responses. Acting like they never have issues is just burying your head in the sand. mDNS often works just fine on most common OSes, if you don't explicitly block them.

[zadikian]

Default home router out of the box is not going to have DHCP issues. Custom config or bigger network, sure, I've dealt with it too.

What network administrator?
