To me the question is why on earth in this day and age are you still running static at home?
I run static IPv4 addresses on computers that are always connected to my LAN. Others use DHCP with IP addresses tied to MAC address. Of course, the IPv6 addresses are always static, based on the MAC addresses, though some devices can also have a random address.
However, I agree there's no point on using a static address for portable devices.
Sometimes static makes sense because it is simple. As James says, statically connected LAN devices are ... Static. N y home system has a firewall/switch/router that CAN do DHCP but why? All the things connected to it are permanently on, More to the point, I access them all from my desktop, which apart from my phone an tablet are the only 'screens. Everything else is 'headless', the router, the printer, the wifi router the voip. So on my desktop I have a /etc/hosts file with all those permanent addresses. I know that DHCP can dish out names, but if its DHCP from my firewall/switch that isn't as well integrated as if I ran it from my desktop Linux machine. While I might take the desktop down the firewall//switch/router is pretty much always up. So please don't tell me that dnsmasq can do DHCP+DNS. I know that. It doesn't apply. It would make sense only if the desktop, the ONLY Linux machine, were doing DHCP. Its not. If I were to use DHCP on the LAN backbone tjhen I would use the DHCP on the firewall/switch/router. As John points out, this was built after the Pleistocene. The wifi router that hangs off the backbone and the voip/ATA that also hangs off the backbone both have Ethernet ports and those run DHCP. But nothing is plugged in there. I still have free ports on the backbone switch. And they will be faster. The desktop is where I do 'maintenance' from, so entering 'http://printer:8080' in firefox there makes sense. There are many situations where DHCP makes sense. An office with transient or 'hotelling' connections, an ISP, many others. But a home system for anyone with subject matter experience -- as opposed to a Joe Sixpack who knows no better than to buy the box the salesman recommends from Best But or Target or Wal-Mart -- to assign permanent addresses, that is anyone with the smarts to run Wicked or NM, and a small set of connected devices, then DHCP offers little if any advantage. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
