This is the correct answer. “Castor” is your systems host name. Some home router/gateways will remember the hostname a system used as part of their network, and when handing out the same IP to a new host, re-uses the saved hostname. I’ve never encountered one of these devices, but I’ve heard of windows systems and even phones can do this. Set your preferred hostname either in GNOME Settings (or whatever DE’s settings) or with hostnamectl. -- Jonathan Billings -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
