_need_, no. Try https://mickmalloy.dyndns.org/remote
One of the other SBS MVPs recently made a disparaging remark about my use of
dyndns for my main email address and I pointed out I had been operating in
such manner 'for several years' (I think about 7yrs if pressed, maybe 4 as
primary and before that as an additional address).
SO, no, you don't need static IP, it can however be greatly beneficial.
Normally the ISP can create PTR records to statics but not dynamics, this
helps with remote systems identifying SPAM. Also, if you have a dynamic IP
and it changes it takes _some time_ for DNS to propogate, _short_ periods
where the actual IP is not reflected in DNS occur.
A point of consideration when dealing with dynamic IPs is how quickly the
ISP re-issues freed IP's. Say I lose my current IP, when I get a new one
software on my SBS automatically updates dyndns but remote systems which may
be behind 'caching DNS servers' may not immediately see the change. If the
IP has been re-issued to another server people wishing to connect to me will
instead be attempting connection to some other server. I use one of the
worst ISP's in the world (AU's primary telecomms provider, Helstra, whoops,
I mean Telstra) but something they have done well in this manner is that
they have a much greater IP block than client base, released IP's go to the
bottom of the allocation list so there is _at least some_ delay before my
'previous IP' will be re-issued.
Yep, get a static, but at a pinch you can do dynamic.
