After running a (probably broken) openvpn script, I have an IP route table where one entry is a URL:

# netstat -r 
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
default 10.0.0.1 0.0.0.0 UG 0 0 0 wlp58s0
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 wlp58s0
google.com 10.0.0.1 255.255.255.255 UGH 0 0 0 wlp58s0

How can I delete this last row? The regular way throws an error:

# ip route del google.com
Error: any valid prefix is expected rather than "google.com".

I'm on gentoo linux, if that matters.

The entry google.com is not a URL; it's a domain name, or possibly a host name. (It could be part of a URL, though.)

If you use netstat -rn you will get IP addresses instead of names in that first column. From there you can delete the route - again by reference to its network and subnet addressing.

netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
default server.roaima 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
google.com 0.0.0.0 255.255.255.255 UH 0 0 0 eth1

netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 192.168.2.2 0.0.0.0 UG 0 0 0 eth1
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
216.58.198.174 0.0.0.0 255.255.255.255 UH 0 0 0 eth1

route delete -host 216.58.198.174

You can also do this with the newer ip route, which lists routes only with IP addresses. Use ip route del to delete the unwanted entry.
