Tor supports SOCKS4a and SOCKS5-with-hostnames, but using SOCKS4 or SOCKS5-with-IP-addresses means that you're probably leaking DNS.

"Torcap" intercepts gethostbyname requests at the C library level, and the projects called "TorDNS" act as local nameservers that relay requests to Tor. Neither is cross-platform, though, and neither supports hidden services correctly. (Supporting hidden services would be doable with the 'MAPADDRESS' command in the control interface, but I don't think anybody's taking that approach yet.) The problem here is not a lack of good ideas but a lack of spare time. Thanks for the ideas though! yrs, -- Nick Mathewson
