Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1420047
Build error leg or test failing: android-arm64 Release AllSubsets_CoreCLR - System.Net.NameResolution.Functional.Tests

Error Details

The test DnsGetHostEntry_LocalhostSubdomain_RespectsAddressFamily(addressFamily: InterNetwork) fails on Android because Dns.GetHostEntry returns IPv6 addresses when only IPv4 (InterNetwork) addresses are expected. The Assert.All() check validates each returned address matches the requested address family.

[FAIL] System.Net.NameResolution.Tests.GetHostEntryTest.DnsGetHostEntry_LocalhostSubdomain_RespectsAddressFamily(addressFamily: InterNetwork)
Assert.All() Failure: 10 out of 12 items in the collection did not pass.
[1]:  Item:  fe80::50fc:71ff:fee7:54f2%47
      Error: Assert.Equal() Failure: Values differ
             Expected: InterNetwork
             Actual:   InterNetworkV6

Note: The prior KBE #124751 covered a different failure mode on the same test (SocketException: hostname nor servname provided) and is now closed. This is a new failure where the DNS resolution succeeds but returns addresses of the wrong family.
