Do you mean expiring the IP address when the TTL is reached? I suppose that could be an issue for a long-running service, and I don't have a good answer to that. Possibly these days with services meshes and load-balancers it is less of a concern since a logging server can move without changing its IP address. But it's important for a logging system not to block the service doing the logging (which is one reason for using UDP in the first place). I only discovered this issue because of some flaky DNS servers that would occasionally take several seconds to answer a query, and block the whole asyncio event loop while it waited. At a minimum it would be useful to document it, so that you know it's something to be concerned about when using DatagramHandler. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47149> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
