Default IP address on HP ProCurve 2510G-24 and 2910al switches
There is no static IP assigned
Need to configure that new ProCurve 2510G-24 or 2910al that just showed up, factory fresh? The IP address is assigned via DHCP. I had to check with my DHCP server to work out which address it was.
If there is no DHCP server, then it will self assign an IP in the 169.254.0.0/16 range via Automatic Private IP Addressing (APIPA), aka "zero configuration networking".
