  • att.net zone: The server(s) were not responsive to queries over UDP. See RFC 1035, Sec. 4.2. (2001:1890:1ff:9f0:68:94:156:128, 2001:1890:1ff:9f0:68:94:156:130)
  • els-gms.att.net to ns.els-gms.att.net: No delegation NS records were detected in the parent zone (els-gms.att.net). This results in an NXDOMAIN response to a DS query (for DNSSEC), even if the parent servers are authoritative for the child. See RFC 1034, Sec. 4.2.2. (68.94.156.128, 68.94.156.130, 99.99.99.128, 99.99.99.130, 2001:1890:1ff:9f1:99:99:99:128, 2001:1890:1ff:9f1:99:99:99:130, UDP_-_EDNS0_4096_D_KN)
