What an ISP Is

An ISP (Internet Service Provider) is the company that sells you access to the internet. When you sign up for a home broadband or mobile plan, the ISP connects your location to the global network, assigns you a public IP address, and carries your traffic to and from the rest of the world. You can see which ISP you're using on What's My IP.

What Your ISP Provides

  • IP address assignment — your public IP, usually via DHCP
  • Routing — moving your data across its network and onward to destinations
  • DNS servers — resolving domain names (though you can use your own DNS)
  • The physical connection — fibre, DSL, or mobile to your premises
  • Support and billing — managing your account and service

How the Internet Hierarchy Works

No single company owns the internet. It's a network of networks, organised loosely into tiers:

TierRoleHow they connect
Tier 1Global backbone carriersSettlement-free peering with each other
Tier 2Regional / national ISPsPeer where possible, buy transit from Tier 1
Tier 3Local access providersBuy most connectivity upstream, sell to users

Your data often passes through several networks — your ISP, one or more transit providers, and the destination's network — before it reaches its target and comes back.

ISPs in the UAE

The UAE operates a licensed duopoly for fixed-line internet:

  • e& (formerly Etisalat) — the original operator, with the widest coverage across all seven emirates and full-fibre plans up to 1 Gbps (2 Gbps in select areas). Test your Etisalat speed.
  • Du — launched in 2007, especially strong in free zones and newer developments, also offering gigabit fibre. Test your du speed.
  • Virgin Mobile UAE — a mobile provider that runs on the Du network. Test your Virgin Mobile speed.

What Your ISP Can See

Your ISP can see the domains you request via DNS and the servers you connect to. Thanks to HTTPS, it usually can't read the content of pages, but it still knows which sites you visit unless you use encrypted DNS and a VPN. It also sees your total data usage and can, in some cases, throttle specific traffic types.

ISP Throttling and Performance

If certain services feel slow only at peak times, your ISP may be throttling or its links may be congested. Compare results from a speed test at different times of day. If your wired speed is consistently well below your plan, that's worth raising with your provider — see why your internet is slow.
