[Gllug] Is my cheapo router really caching DNS?

[Adrian McMenamin]

Having read a quite good introduction to djbdns in the latest issue of
Linux Journal I am tempted to set up a caching DNS server on my network,
except that my router (a piece of cheap commodity kit) claims to be
doing this already (see below). Is it really, or is it just redirecting
these elsewhere and how can I tell?
