I can access my home network from elsewhere via either of these:
Are either or both of these guaranteed to continue to work, or can they arbitrarily change at any time?
(Note that the two XXXXXXs are identical.)
This is what I do.
I used to use DYNDNS until they started charging 😞
I am using No-ip. Its basic service is free, but if your IP doesnt change within a month and isnt updated to something new, it will notify you that it will be removed unless renewed... I get an email, do the quick renewal.
I have a small webserver running at home. I have a registered domain, but I point that do the dynamic services address. Then just update it.
