}The ::marker pseudo-selector can be used to customize the rest. Generating content for markers is supported by Chromium and Firefox, but not by WebKit.
A list of symbols can be used with symbols(). The browser support is not great though. @counter-style can be used instead. It's Baseline Newly Available since 2023.
There is also the old ::before trick to set custom contents.
As summary:
| CSS | Use Case |
|---|---|
| list-style | Changing the basic bullet styles or numbering system. Using a Unicode symbol, emoji or text in place of a bullet. Using images for bullets. |
| li::marker | Colouring the numbering or bullets differently to the list text. Changing the font- properties of the numbering (but not its size unless the difference is subtle). |
| symbols() | Only supported by Firefox, use @counter-style instead. |
| @counter-style | For defining your own sequence of bullet symbols (not images) or a completely customised numbering system. |
| extends | Used within @counter-style to modify existing numbering systems, for example to change or remove the default ”.” suffix. |
| li::before | For complete control over marker positioning, especially if your bullets or numbering are much larger than the list text. |
An IPv6 can de divided into 3 pieces:
- 48 or more bits of network identifier (also known as the subscriber prefix)
- 16 or fewer bits of subnet identifier
- 64 bits of interface identifier
The RFC mentioned can be obsolete, but are kept up to date at
Using MAC adresses was flawed, and location data was too. The randomization defined in RFC 30411 was then refined in RFC 7217. Here comes the SLAAC protocol.
Steps:
- Calculating a link-local address
- Link-local Duplicate Address Detection (DAD)
- Locating a router (by sending a Router Advertisement (RA) message)
- Calculating a routable address
DHCPv6 (RFC 3315) solves also the domain name association with IPv6 while distributing additional information.
There is an address renegotiation to preserve privacy.
Slaac is vulnerable to RA spoofing, and DNS spoofing. The proposed solution is to use IPsec, but it's complicated to deploy. SEcure Neighbor Discovery introduced a dedicated cryptographic authentication protocol for network discovery.
Another potential issue is that a network device can respond with Neighbor Advertisement packets for every Neighbor Discovery it sees. This will effectively block any device from completing Duplicate Address Detection, hence blocking SLAAC from completing. Preventing this attack is a current research topic 1, 2, 3
