A static IP without the business theatre

A number that does not change is a tool. It is not a status, and it is not a reason to sit on a business tariff you do not need.

IPv4 addresses became jewellery. People who need to reach a home lab, a camera, a tiny server, get told they must become a business, with a business SLA, a business cease path, and a business smile. Sometimes that is the honest product. Often a residential static, or even a dynamic DNS plus a hole in CGNAT, would have done. The theatre is expensive. The number is cheap.

Do you need it

Inbound access you care about, work allow-lists, some VPNs, some payment terminals. If you only browse and join calls, you do not need a static. You need upload.

If you cannot accept inbound because you are on CGNAT, you need a public address — static is the convenient form of public.

Buy the add-on, not the costume

Several household ISPs will sell a static on a consumer contract. That keeps you inside One Touch Switch and away from business cooling-off folklore.

If the only way to get an address is a business product, read the cease rules twice. Business lines are not always in the consumer hub.

Switching with an allow-list

Tell the office. Change the DNS. Expect a new number. If a vendor has had your IP for five years, the switch project is that vendor, not Ofcom.

Do not stay on a punitive rolling tariff because an allow-list is sticky. Sticky is a calendar reminder, not a marriage.

A static IP is a number. A business tariff is a legal mood. Know which you were sold.

Addresses are scarce and useful. Costumes are abundant. Pay for the former if you need it, and skip the lanyard if you do not.

Questions

Will a static IP make me faster?
No. It makes you reachable. Speed is a different shop.
Is CGNAT ‘bad’?
It is a way to share scarce IPv4. Bad for inbound. Invisible for Netflix. Know which you are.
Can I keep the IP when I switch?
Almost never on residential. Plan a DNS cut. If the IP is in allow-lists at work, tell work the week before.
Do I need a business contract for a static?
Some retailers say so. Others sell it as a £5 add-on. Shop the add-on, not the theatre.
What about IPv6?
A prefix that is stable-enough can replace a lot of static-IPv4 theatre — if the other end speaks v6. Many offices do not.
