[1 mark]
  • A192.168.1
  • B192.168.1.1
  • C192.168.1.1.1
  • D192.168.1.256
Mark scheme
  • B 192.168.1.1 (1)
  • The only correct answer is B. The correct answer is 192.168.1.1.
  • A is not correct because it is an incomplete address with only three numbers, not four
  • C is not correct because it is an address with five numbers, not four
  • D is not correct because it contains 256, which is outside the range 0 to 255
Example answers and how they were marked
Full marks1/1

B 192.168.1.1

Why: Correct option (1): an IPv4 address is four numbers, each from 0 to 255, separated by dots.

No marks0/1

D 192.168.1.256

Why: Near miss: it has four numbers but 256 is outside the range 0 to 255 (mark scheme line D), so no mark.

No marks0/1

A 192.168.1

Why: It has only three numbers, so it is not a complete IPv4 address (mark scheme line A), so no mark.

Define the term IP address.

[2 marks]
Mark scheme

Award one mark for any of the following up to a maximum of two marks:

  • A unique identifier/number (1)
  • Given to a device on a network/the internet (1)
  • Used to send/receive/route data (to the correct destination) (1)

Allow computer/laptop/phone/printer etc. for device.

Do not accept a website address/domain name.

Do not accept MAC address (this is a hardware identifier set by the manufacturer, not an address given to a device for use on a network).

Do not accept 'an address'/'a location' on its own, without saying that it identifies a device on a network/the internet.

Example answers and how they were marked
Full marks2/2

A unique number given to a device on the internet so that data can be sent to it.

Why: Unique identifier (1) and given to a device on the internet (1); the third creditworthy point is not needed for full marks.

Some marks1/2

A unique number.

Why: Gives a unique identifier (1) but does not say what it is given to or what it is used for.

No marks0/2

The address of a website, such as google.co.uk.

Why: Describes a domain name/website address, not an IP address; the Do not accept line applies.
