Is there any reason in particular that you think you need a static IP?
In general, it’s A Bad Idea(TM), unless you are running your own Internet
server with multiple services. It gets even trickier if you are running a
static IP in combination with other devices that use dynamic IPs and/or local
(non-routed) IPs.
One problem is often with too-long “time to live” on DNS servers and stale
routing tables. Everyone between you and what you are trying to access have to
flush you from their routing tables. It should resolve, over time, but if you
ISP then changes your dynamic IP block, you will see the routing issue come up
again.
You really need to provide your own authoritative reverse-DNS record for the
static IP, which makes things more complicated, too. There are lots of sites
that won’t talk to you unless you have a proper reverse-DNS record.
I’ve had at least one static IP since the 90s, and it is a pain in the butt
that I would not consider, except that I also run my own web server, mail
server, DNS server, VPN server, and other special services.
I’m currently tracking down a problem where, every few weeks, all my dynamic
IPs and local IPs stop working (the static IP continues to work), at which
point, re-starting the ISP’s router fixes things, but it takes my static server
“off the air” for several minutes while it re-boots. This seems to happen when
my ISP changes my DHCP block. I try to explain that they need to flush the
routing tables when they do that, but then someone in India tells me to turn it
off and then on again. :-(
