Method and system for preventing service disruption of internet protocol (IP) based services due to domain name resolution failures
摘要：
A method for preventing service disruption for a device in a network is provided. The method includes populating a filter list with an IP address declared to be valid for a server in the network and populating a rainy day list with an IP address discovered to be valid for the server. The method also includes requesting a DNS server to resolve a server domain name to a server IP address. When no response to the request is received, an IP address on the rainy day list is used to attempt to contact the server. When a response is received, the received IP address is compared to an IP address on the filter list or the rainy day list. When the received IP address matches an IP addresses on the filter list or the rainy day list, the received IP address is used to contact the server.
摘要（中）：

提供一种用于防止网络中的设备的服务中断的方法。 该方法包括填充具有被声明为对网络中的服务器有效的IP地址的过滤器列表，并填充已发现对服务器有效的IP地址的下雨天列表。 该方法还包括请求DNS服务器将服务器域名解析为服务器IP地址。 当没有接收到对请求的响应时，使用雨天列表上的IP地址尝试联系服务器。 当接收到响应时，将接收的IP地址与过滤器列表或雨天列表上的IP地址进行比较。 当接收的IP地址与过滤器列表或雨天列表上的IP地址相匹配时，接收的IP地址用于联系服务器。
