If it's DHCP, your defaultrouter definition is overridden every time you get/renew a lease. netstat -r -n -f inet | grep -v link tells where your packets go next. But in any case, it's helpful to know how traceroute works. It usually sends UDP packets with increasing TTLs which are supposed to elicit an ICMP error message (TTL expired) from hops along the way. The IP address you get a response from may be different from what you expect, especially when navigating the innards of your ISPs switch fabric. It's possible that it isn't even the address of any interface on any router. On the intermittent failure issue - are you running a firewall? Do you permit 67-68/udp between your gateway and the ISP? And did Surewest get acquired by XO? - M
