Unfortunately, client support for history playback is still patchy. In descending order of support:
1. The [IRCv3 chathistory specification](https://github.com/ircv3/ircv3-specifications/pull/393/) offers the most fine-grained control over history replay. It is supported by [Kiwi IRC's unreleased master branch](https://kiwiirc.com/), and hopefully other clients soon.

1. We emulate the [ZNC playback module](https://wiki.znc.in/Playback) for clients that support it. You may need to enable support for it explicitly in your client (see the "ZNC" section below).
1. If you are not using the multiclient functionality, but your client is set to be always-on (see the previous section for details), Oragono will remember the last time your client signed out. You can then set your account to replay only messages you missed with `/msg NickServ set autoreplay-missed on`. Unfortunately, this feature will only work reliably if you are *not* using the multiclient functionality described in the above section --- you must be connecting with at most one client at a time.
1. You can manually request history using `/history #channel 1h` (the parameter is either a message count or a time duration). (Depending on your client, you may need to use `/QUOTE history` instead.)

IP cloaking is a way of balancing these concerns about abuse with concerns about user privacy. With cloaking, the user's IP address is deterministically "scrambled", typically via a cryptographic [MAC](https://en.wikipedia.org/wiki/Message_authentication_code), to form a "cloaked" hostname that replaces the usual reverse-DNS-based hostname. Users cannot reverse the scrambling to learn each other's IPs, but can ban a scrambled address the same way they would ban a regular hostname.
Oragono supports cloaking, which can be enabled via the `server.ip-cloaking` section of the config. However, Oragono's cloaking behavior differs from other IRC software. Rather than scrambling each of the 4 bytes of the IPv4 address (or each 2-byte pair of the 8 such pairs of the IPv6 address) separately, the server administrator configures a CIDR length (essentially, a fixed number of most-significant-bits of the address). The CIDR (i.e., only the most significant portion of the address) is then scrambled atomically to produce the cloaked hostname. This errs on the side of user privacy, since knowing the cloaked hostname for one CIDR tells you nothing about the cloaked hostnames of other CIDRs --- the scheme reveals only whether two users are coming from the same CIDR. We suggest using 32-bit CIDRs for IPv4 (i.e., the whole address) and 64-bit CIDRs for IPv6, since these are the typical assignments made by ISPs to individual customers.

Setting `server.ip-cloaking.num-bits` to 0 gives users cloaks that don't depend on their IP address information at all, which is an option for deployments where privacy is a more pressing concern than abuse. Holders of registered accounts can also use the vhost system (for details, `/msg HostServ HELP`.)

## Kiwi
[Kiwi IRC](https://github.com/kiwiirc/kiwiirc/) is a web-based IRC client at the bleeding edge of IRCv3 support. In particular, it is the only major client to support fully Oragono's server-side history features. For a demonstration of these features, see the [Oragono testnet](https://testnet.oragono.io/kiwi).
Current versions of Kiwi are 100% static files (HTML and Javascript), running entirely in the end user's browser without the need for a separate server-side backend. This frontend can connect directly to Oragono, using Oragono's support for native websockets. For best interoperability with firewalls, you should run an externally facing web server on port 443 that can serve both the static files and the websocket path, then have it reverse-proxy the websocket path to Oragono. For example, configure the following listener in ircd.yaml:
```yaml
"127.0.0.1:8067":
websocket: true
```
then the following location block in your nginx config (this proxies only `/webirc` on your server to Oragono's websocket listener):
```
location /webirc {
proxy_pass http://127.0.0.1:8067;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
}
```
then add the following `startupOptions` to Kiwi's `static/config.json` file (see the [Oragono testnet's config.json](https://testnet.oragono.io/kiwi/static/config.json) for a fully functional example):
```
"startupOptions" : {
"websocket": "wss://domain.example.com/webirc",
"channel": "#chat",
"nick": "kiwi-n?"
},
```
## Hybrid Open Proxy Monitor (HOPM)
[hopm](https://github.com/ircd-hybrid/hopm) can be used to monitor your server for connections from open proxies, then automatically ban them. To configure hopm to work with oragono, add operator blocks like this to your oragono config file, which grant hopm the necessary privileges:
