DNS服務工具 Dnsmasq 2.59 發布

DNSmasq是一個輕巧的，容易使用的DNS服務工具，它可以應用在內部網和Internet連接的時候的IP地址NAT轉換，也可以用做小型網絡的DNS服務。

該版本修復了 2.58 中的很多bug，特別是 IPv6 下啟動的問題。

Dnsmasq provides the following features:

The DNS configuration of machines behind the firewall is simple and doesn't depend on the details of the ISP's dns servers

Clients which try to do DNS lookups while a modem link to the internet is down will time out immediately.

Dnsmasq will serve names from the /etc/hosts file on the firewall machine: If the names of local machines are there, then they can all be addressed without having to maintain /etc/hosts on each machine.

The integrated DHCP server supports static and dynamic DHCP leases and multiple networks and IP ranges. It works across BOOTP relays and supports DHCP options including RFC3397 DNS search lists. Machines which are configured by DHCP have their names automatically included in the DNS and the names can specified by each machine or centrally by associating a name with a MAC address in the dnsmasq config file.

Dnsmasq caches internet addresses (A records and AAAA records) and address-to-name mappings (PTR records), reducing the load on upstream servers and improving performance (especially on modem connections).

Dnsmasq can be configured to automatically pick up the addresses of its upstream nameservers from ppp or dhcp configuration. It will automatically reload this information if it changes. This facility will be of particular interest to maintainers of Linux firewall distributions since it allows dns configuration to be made automatic.

On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6 and offer DNS service via IPv6. On dual-stack (IPv4 and IPv6) boxes it talks both protocols and can even act as IPv6-to-IPv4 or IPv4-to-IPv6 forwarder.

Dnsmasq can be configured to send queries for certain domains to upstream servers handling only those domains. This makes integration with private DNS systems easy.

Dnsmasq supports MX and SRV records and can be configured to return MX records for any or all local machines.
