Class C changes the third number in an address. Class B changes the second. Class A changes the first: the widest separation two IPv4 addresses can have. American addresses, private nameservers on every domain, cPanel and free SSL.
3 to 20 Class A IPs · USA · one flat rate at every quantity
Need Europe instead? →Every other product we sell gets cheaper per unit as you buy more. This one does not, and the reason is worth understanding before you order.
Volume pricing exists where the marginal cost of the next unit falls. On Class C it genuinely does: your four-hundredth address rides the same racks and upstream as your first, so the rate drops in bands.
Class A is a different product. What you buy is not capacity; it is a first octet, and only 255 of those exist. Your twentieth address consumes exactly as scarce a resource as your first, so pretending it is cheaper would be an accounting fiction. We price it honestly: $8.50 per IP per month, from 3 to 20 addresses.
An IPv4 address has four octets: a.b.c.d. Which one differs between two of your sites decides how far apart they look from the outside. Move the third and you change neighbourhood. Move the second and you change parent network. Move the first and there is nothing left to move.
We will not tell you an octet is a ranking factor: it is not. What first-octet separation removes is a shared pattern: a common upstream, a common reputation history, a common allocation record. On a Class C network that pattern survives at the top. On a Class A network there is no top left for it to survive in.
The first octet of an IPv4 address is a single eight-bit number. That is the entire supply: 255 non-zero values, 255 first-octet blocks, for the whole IPv4 internet. Not 255 per registry, not 255 per continent: 255 in total, with no mechanism anywhere that can produce a two hundred and fifty-sixth.
Nearly all were allocated in the 1980s and early 1990s to governments, tier-one carriers, universities and a few corporations that were online before most people knew the internet existed. They rarely come back to market. This is the one part of hosting where the constraint is not money or engineering: the supply was fixed before the product was invented.
SEOHost can allocate customer addresses out of 10% of those blocks: roughly 26 distinct first octets. That number is also why a USA order stops at 20: it is the ceiling that guarantees every address in your order gets its own first octet, rather than two of your sites quietly sharing a top-level range.
The same stack whether you take 3 addresses or 20. None of these is a paid add-on.

Region decides which pool your addresses come out of, how far your pages travel to the audience you are ranking for, and whose law your hosting contract answers to.
The American side holds 800 dedicated IPs against 500 in Europe, inside 1,300+ distinct Class C blocks. Depth is what stops a scarcity product from quietly recycling the same few ranges, and it is why USA Class A runs to 20 addresses while Europe stops at 20.
If the search results you care about are American, the servers should be too. A page served from Detroit reaches a US visitor in a fraction of the time it takes to cross the Atlantic, and server response feeds straight into Largest Contentful Paint: the Core Web Vital most sites fail. Our US machines run LiteSpeed with LSCache.
Hardware in the United States sits under United States law, with the notice-and-takedown process American businesses already understand. For a network built around US clients and US search intent, keeping hosting in the same jurisdiction removes a category of surprises. Prefer European data-protection rules? The identical product exists in Europe.
US Class A addresses are not all handed out from one rack in one room. Our American footprint spans more than one datacenter, so a network can vary its first octet and its physical location without leaving the region. Adding European addresses later is one more order, not a migration.
Not sure the USA is the right side? The same product exists in Europe with its own pool and its own ceiling: Class A IP hosting in Europe from $3.60/IP/mo on a 3-year term →
No manual review, no ticket queue, no human to wait for. Provisioning is automated and runs 24/7, so your Class A allocation is active the moment payment clears.

Three tiers of the same idea, priced by how scarce the separation is. Class A is the ceiling: nothing separates two IPv4 addresses further, and nothing is harder to get.
