Glossary Entry
What is IP Address?
IP Address without the jargon — the definition, the analogy, and why any site owner should care.
The short answer
An IP address is a machine's numeric identity on the network, the real destination sitting behind every domain name you type.
The rest of the page opens it up — the mechanics, why a site owner should care, and one concrete example of it at work.

To read, always
IPv4's dotted numbers, such as 203.0.113.10, are scarce enough that shared hosting puts many sites behind one address and lets the server separate them by the hostname carried in each request. A dedicated address holds the number for one customer.
Reputation sticks to addresses. Whatever an address has done before travels with the mail leaving it, which is why serious senders are so particular about their neighbours.
A way to picture IP Address
The grid reference beneath a place name. The name exists so people can remember it, and the coordinates are what the navigation system actually steers by.
Any analogy flattens the detail, naturally — but this one is solid enough to think with, and thinking is what a jargon buster is for.
Why this term earns a page
Addresses turn up in real decisions: dedicated ones where an integration insists, mail reputation on a VPS, firewall rules, and server logs where every visitor is a number before they are anything else.
That, incidentally, is the bar for any technical term — not 'could I lecture on it' but 'would I recognise it as the answer to my problem'. For this one, you now would.
How it turns up day to day
Part of what gets a VPS owner's mail delivered is the unblemished record of the address it left from, which is one reason a dedicated IPv4 comes with every VPS plan we sell.
Scale that example across every website online and you have described the whole job of the concept in one stroke.
Where it appears on this platform
You will meet it in the control panel and now and then in a support thread, usually already set correctly. If this one landed, the natural follow-ups are IPv6, A Record, DNS and VPS.
Order an annual plan and the first year of the name's registration is on us.
A jargon buster from the people who answer the tickets
An unexplained piece of jargon is, to us, a service defect. This is the support team's collected translations, published where a search engine can hand them over on our behalf.
A copy is taken daily on every plan, and putting a file or a database back is one click in the panel rather than a support ticket.

Why Hosting & Domains
Standard on every plan
Analogies that hold
Every concept comes with a mental model that returns exactly when you need it.
This term, properly landed
IP Address defined, pictured by analogy and located in your own panel — recognise-level after a single read.
Clear about how deep to go
Most of these are recognise-level rather than operate-level, and every entry says which it is.
Cross-wired entries
Related terms point at each other, so one lookup compounds into working knowledge.
The next step, drawn out
Carry on into IPv6 and A Record — ideas rarely travel alone, so the neighbours are linked in.
Tied to real hosting
Examples name platforms you would genuinely use, never an abstract diagram on a whiteboard.
Quick Start
Order placed to site online
- 1
Find it in your own account
Open the control panel and find where this idea sits — a definition turns into understanding the moment it attaches to your own site.
- 2
Check the defaults as they stand
The platform ships sensible defaults for this — check rather than assume, and your setup becomes something you know instead of hope.
- 3
Chase the neighbouring terms
Hosting terms travel in groups — IPv6, A Record and DNS finish this one's picture, each a two-minute read away.

Frequently Asked
The questions that come up most
Does my website need a dedicated IP?
Rarely for the site itself. SNI ended the one-certificate-per-address era and shared addresses serve websites perfectly well. Genuine reasons do exist: a few legacy integrations, certain firewall allow-list arrangements, and holding your own mail reputation on a server you send from.
Can people find my home address from my site's IP?
What it identifies is the server, meaning the datacentre and the host, and never your home. Your own location appears nowhere in the routing. It exists only in whatever contact details you choose to publish, which is an entirely separate decision.
What is the refund position if I change my mind?
Shared, business, WordPress and WooCommerce hosting get thirty days, and reseller gets seven. VPS and dedicated servers are built to order the moment payment lands, so they sit outside the guarantee — as do domain registrations, where the registry charges the instant the name is secured. Inside the window one request returns the hosting fee, with no retention script to sit through.
Who stands behind Hosting & Domains?
