Dedicated IP vs Shared IP

Quick answer

A shared IP is one address used by many hosting accounts; a dedicated IP is used by your server alone. Thanks to SNI, a shared IP handles SSL normally, and Google does not rank by IP. Choose a dedicated IP only for regular bulk email, a custom PTR record, or partner, bank or broker IP allowlisting.

For site owners and developers deciding whether a dedicated IP is worth paying for, or whether a shared address already does the job.

What is the difference between a shared IP and a dedicated IP?

A shared IP is one public IPv4 address that many hosting accounts answer on; a dedicated IP is an address that only your server or account uses. The web server tells sites apart on a shared address by the domain name in each request, so visitors never notice the difference.

Shared IP vs dedicated IP, attribute by attribute
Attribute	Shared IP	Dedicated IP
Who answers on it	Many accounts on one server	Only you
Where you get it	Included with shared hosting	Usually included with a VPS or dedicated server; an add-on elsewhere
Mail reputation	Pooled with neighbours, already warm	Yours alone, starts cold
Reverse DNS (PTR)	Set by the host to the server name	Can be set to your own mail hostname
Open the site by typing the IP	No, shows the server default page	Yes
Firewall allowlisting by partners	Not reliable, address can change	Yes, fixed address

An IP address is not a security boundary. Accounts on the same shared address cannot read each other's files or mail; isolation is enforced by the account and file permissions on the server.

Do you need a dedicated IP for an SSL certificate?

No. Server Name Indication (SNI) lets one IP address serve a different certificate for every domain, and all current browsers and phones send SNI. A site on a shared IP gets the same padlock and the same encryption as one on a dedicated address.

The "dedicated IP for SSL" rule dates from the era of Internet Explorer on Windows XP and Android 2.x, which could not send SNI. If an old point-of-sale terminal or embedded device must reach your site, test it, but that is a rare exception. WebJi® shared plans include free SSL on the shared address, and free vs paid SSL explains when a paid certificate is worth it.

Does a dedicated IP improve SEO or speed?

No. Google evaluates pages and sites, not the IP address they share, and a manual action applies to the site that broke the guidelines, not to its neighbours. Search ranking does not change when the address does.

Speed is the same story. The IP is just an address; if a shared server is slow, the cause is CPU, memory or disk contention, and a second IP on the same busy machine changes nothing. The real fix is reserved resources, which is the jump from shared hosting to a VPS covered in shared vs VPS hosting.

When is a dedicated IP worth having?

A dedicated IP is worth it when something outside your website depends on a fixed address: high-volume email, partner or bank allowlists, broker API access, or a custom reverse DNS name.

Regular bulk email

Large, steady sending builds a reputation you control instead of sharing a neighbour's. It needs warm-up and consistent volume; occasional sends leave the address cold.

IP allowlisting

Payment gateways, banks, ERP systems and government portals often accept API calls only from registered addresses.

Algo-trading APIs

Indian brokers now ask retail algo traders to register a static IP for API orders; see the SEBI static IP rule.

Own mail server

Receivers check that the PTR record matches the sending hostname, which you can only control on your own IP. The PTR record guide explains it.

Shared IP vs dedicated IP for email deliverability

For a business sending everyday mail and a modest newsletter, a well-run shared IP usually delivers better than a dedicated one, because its reputation is already established and kept clean by the host. A dedicated IP only pays off when you send enough, every week, to keep it warm.

Authentication first: SPF, DKIM and DMARC on the sending domain matter more than the address. Set them up with the SPF and DMARC guide.
Warm-up: a new dedicated IP should start with small daily volumes to engaged recipients and grow over several weeks.
Domain reputation travels with you: Gmail and Outlook judge the From domain as well as the IP, so a spammy list fails on either.
Blocklists: if a shared neighbour gets the address listed, the host can move you; with a dedicated IP, delisting is your job. Check status with the blacklist checker.

How to check whether your site is on a shared IP

Look up your domain's IP, then run a reverse lookup on that IP; a generic server hostname, or other sites resolving to the same address, means it is shared.

# the IP your domain points to
dig +short example.in A

# the name the IP owner assigned to that address
dig +short -x 203.0.113.25

# Windows equivalents
nslookup example.in
nslookup 203.0.113.25

Run the first command, or use the DNS lookup tool, and note the IPv4 address.
Run the reverse lookup. A name like server42.hostingcompany.net indicates a shared server; your own hostname suggests a dedicated address.
Paste the IP into your browser. A host's default page instead of your site means the address is shared.
If in doubt, ask the host: only they know which accounts use that address. More methods are in finding the IP address of a domain.

Dedicated IPs at WebJi®

WebJi® shared hosting runs on the server's shared IP with free SSL; a dedicated address comes with a VPS or dedicated server, quoted in INR before payment. If the need is purely a fixed address for broker or bank allowlisting, the static IP VPS page covers that setup. Email support@webji.services, 24/7 in Hindi and English, to have your mail volume or allowlisting need checked before you decide.

FAQ

Frequently asked questions

Will a dedicated IP stop my emails going to spam?

Not by itself. A cold dedicated IP with low or irregular volume can do worse than a warm shared one. Fix SPF, DKIM and DMARC, clean the list and send to engaged recipients first; then a dedicated IP helps only if you send in volume every week.

Can a bad neighbour on a shared IP get my site blocked?

Your website stays reachable, but outgoing mail from that server can be affected if a neighbour's spam lands the IP on a blocklist. Hosts monitor this and suspend abusive accounts or move mail to a clean address.

Does a VPS come with a dedicated IP?

Usually yes. A VPS or dedicated server normally includes at least one public IPv4 address used only by that machine, and you can ask for a custom reverse DNS name. Extra IPv4 addresses are often available on request, subject to the provider's allocation.

Is IPv6 a replacement for a dedicated IPv4?

Not yet for most uses. Many Indian broadband users and corporate networks still reach sites over IPv4, and bank or broker allowlists usually ask for an IPv4 address. Run both where possible; IPv4 vs IPv6 explains the differences.
