Whether to insert or delete the object from the array. If you want
to change an IPSetDescriptor
object, you delete the existing
object and add a new one.
The IP address version, IPv4
or IPv6
.
The IP address in CIDR notation, for example, 192.0.2.0/24
(for
the range of IP addresses from 192.0.2.0
to 192.0.2.255
) or
192.0.2.44/32
(for the individual IP address 192.0.2.44
).
AWS WAF supports IPv4 address ranges: /8 and any range between /16
through /32. AWS WAF supports IPv6 address ranges: /24, /32, /48, /56,
/64, and /128. For more information about CIDR notation, see the
Wikipedia entry Classless Inter-Domain Routing.
IPv6 addresses can be represented using any of the following formats:
You use an IPSet
to specify which web requests you want to allow or
block based on the IP addresses that the requests originated from. For
example, if you're receiving a lot of requests from one or a small
number of IP addresses and you want to block the requests, you can
create an IPSet
that specifies those IP addresses, and then configure
AWS WAF to block the requests.
To create and configure an IPSet
, perform the following steps:
Submit a CreateIPSet request.
Use GetChangeToken to get the change token that you provide in the
ChangeToken
parameter of an UpdateIPSet request.
Submit an UpdateIPSet
request to specify the IP addresses that you
want AWS WAF to watch for.
When you update an IPSet
, you specify the IP addresses that you want
to add and/or the IP addresses that you want to delete. If you want to
change an IP address, you delete the existing IP address and add the new
one.
You can insert a maximum of 1000 addresses in a single request.

HTTP requests, see the AWS WAF Developer Guide.
