Unknown IP on "Active Connections" - ISP's DHCP Server?
Posted: Mon Mar 31, 2014 10:22 pm
I've used routers with alternative firmware (mostly dd-wrt) on my home network for years, but am brand new to Gargoyle (1.6.0)
When I look at the Connected Hosts page, I see one strange entry:
hostname: (unknown)
host ip: 142.254.204.93 (owned by Time Warner Cable, my ISP)
host mac: unknown
Active TCP Cxns: 0
Recent TCP Cxns: 0
UDP Cxns: 1
I sort of got nervous to see a non-local IP active on my router.
Looking further at "Connection List" (current connections), I see:
udp
from: 142.254.204.93:67
to: 255.255.255.255:68
which I suppose is the 1 UDP connection listed.
I did a little searching, and it appears that this describes the DHCP protocol where my router would pull an IP address from Time Warner, as described here:

Is this expected? I've searched the forum, and found several "what is this address doing here" threads. None of the ones I found had any clear answer.
