dns.lookup is not a function. (In 'dns.lookup', 'dns.lookup' is undefined) #46

use rn-nodeify in webtorrent & react-native, console print 'dns.lookup is not a function. (In 'dns.lookup', 'dns.lookup' is undefined)'. cannot node dns module directly replace by dns.js? thanks.

lookup is not supported, use resolve instead if you can. See https://nodejs.org/api/dns.html#dns_implementation_considerations

Under the hood, dns.lookup() uses the same operating system facilities as most other programs.

the currently used shim dns.js is pure javascript (not native). If you really need lookup, you'll need to implement a native shim
