NAME AnyEvent::DNS::EtcHosts - Use /etc/hosts before DNS SYNOPSIS use AnyEvent::DNS::EtcHosts; use AnyEvent::DNS; my $cv = AE::cv; AnyEvent::DNS::any 'example.com', sub { say foreach map { $_->[4] } grep { $_->[1] =~ /^(a|aaaa)$/ } @_; $cv->send; }; use AnyEvent::Socket; my $cv = AE::cv; AnyEvent::Socket::resolve_sockaddr $domain, $service, $proto, $family, undef, sub { say foreach map { format_address((AnyEvent::Socket::unpack_sockaddr($_->[3]))[1]) } @_; $cv->send; }; DESCRIPTION AnyEvent::DNS::EtcHosts changes AnyEvent::DNS behavior. The /etc/hosts file is searched before DNS, so it is possible to override DNS entries. The DNS lookups are emulated. This resolver returns the standard DNS reply based on /etc/hosts file rather than real DNS. You can choose different file by changing `PERL_ANYEVENT_HOSTS' environment variable. This module also disables original AnyEvent::Socket's helper function which reads /etc/hosts file after DNS entry was not found. It prevents to read this file twice. The AnyEvent::Socket resolver searches IPv4 and IPv6 addresses separately. If you don't want to check the addresses in DNS, both IPv4 and IPv6 addresses should be placed in /etc/hosts or the protocol family should be set explicitly for `resolve_sockaddr' function. SEE ALSO AnyEvent::DNS, AnyEvent::Socket. BUGS This module might be incompatible with further versions of AnyEvent module.
