[jira] [Commented] (PROTON-2656) [proton-dotnet] Loopback IP Address lookup can fail on some systems
[ https://issues.apache.org/jira/browse/PROTON-2656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17640268#comment-17640268 ]

Commit 010aced388f3cbc73a03065d4c3e8e668263fd3c in qpid-proton-dotnet's branch refs/heads/main from Timothy Bish
[ https://gitbox.apache.org/repos/asf?p=qpid-proton-dotnet.git;h=010aced ]
PROTON-2656 Try to parse address strings as IP address values first
Instead of going into DNS lookup APIs for all string address values we can
first attempt a parse to see if we have a raw IP Address and simply use
the value given as what was intended.

> When resolving an IP Address from the string form the client uses a DNS entry lookup but for some addresses like local host (127.0.0.1) the DNS entry returned can contain the machine address first which matches the basic criteria and is hard to validate isn't what was intended based on the limited API. We can first attempt a straight parse for raw IP Address vs a host name value and use the raw parsed value as truth instead of going to the DNS lookup API.
