需求描述
有很多域名需要解析到A记录,有的需要解析到CNAME记录,以下两个函数解决这个问题

import dns.resolver


def get_a_answer(vDomain):
    try:
        vIP = dns.resolver.query(vDomain, 'A')
        return str(vIP[0])
    except Exception as e:
        print(e)
        print("ERROR MARK-6dDC0e1394DaEb3E")
        print("ERROR WRONG function get_a_answer() aDomainName -- aIP")
        return '1.1.1.1'


def get_cname_answer(vDomain):
    try:
        vCName = dns.resolver.query(vDomain, 'CNAME')
        return str(vCName[0].target).strip('.')
    except Exception as e:
        print(e)
        print("ERROR MARK-Efba08cfd382Aa61")
        print("ERROR WRONG function get_cname_answer() aDomainName -- aCName")
        return 'www.some.com'
