DNS Proxy Bug on TI Routers



A subtle bug with the dns proxy (dproxy) module on TI MontaVista Linux based routers has been clarified.
Happens with Linux systems with IPv6 enabled applications. IPv6 DNS resolution would return 1.0.0.0. This happens for me with wget.
Affected models include Linksys WRT54G and friends, Aztech DSL600Exx, Dlink (forgot the model).

Solution: Restrict to IPv4 operation with wget -4, or patch dproxy-nexgen to deal with IPv6 queries (how?).
