How to query v4 and v6 networks

[kotronis-te]

Hi, I have two routes in BIRD's RIB, one for v4 prefix 10.1.1.0/24 and one for v6 prefix 2001:db8:3c4d::/48.
I am using birdwatcher's route_net endpoint, and specifically:

r.GET("/route/net/:net", endpoints.Endpoint(endpoints.RouteNet))

I have two questions:

• For v4, I can only query without the netmask, like

/route/net/10.1.1.0

Is there a way to query with the netmask?

• For v6, I cannot get the query to work at all, possibly due to the : format. Do you have a practical example of a working v6 query?

/route/net/2001:db8:3c4d::

Same question about the netmask too, as long as v6 works of course.

Btw for the netmask inclusion, it seems that validation is fine

func ValidatePrefixParam(value string) (string, error) {
	return ValidateLengthAndCharset(value, 80, "1234567890abcdef.:/")
}

however I am not sure how to pass the netmask, escaping the / does not seem to work. Maybe due to this underlying issue?
julienschmidt/httprouter#208

Also regarding the v6, it seems that by default the lookup is in the master table

func RouteNet(r *http.Request, ps httprouter.Params, useCache bool) (bird.Parsed, bool) {
	net, err := ValidatePrefixParam(ps.ByName("net"))
	if err != nil {
		return bird.Parsed{"error": fmt.Sprintf("%s", err)}, false
	}

	return bird.RoutesLookupTable(useCache, net, "master")
}

so it actually needs to use the /table/master6 extension for v6.

However, let me know if you have any ideas or working examples w.r.t. the netmask inclusion in the :net param...

Btw it seems that there is some v4/v6 distinction for bird and bird6 here:

birdwatcher/bird/bird.go

Line 319 in fc7cf5b

return cmd + " where net.type = NET_IP" + IPVersion

This should not apply for bird2 right? I.e., the query should detect the version of the network and use that one, and not set everything on the application layer.

I issued a PR for the v6 problem when looking up routes (tested locally and works):
#52

However, it can probably be closed if you merge #30

I will issue a separate PR for the netmask endpoint
