I think we should also account for allowedHosts: ['host1.com', 'host2.com', 'all']:

webpack-dev-server/lib/Server.js

Line 1516 in 8a3f0d8

if (this.options.allowedHosts === "all") { 

- if (this.options.allowedHosts === "all") { 
+ if (
+ this.options.allowedHosts === "all" || 
+ (Array.isArray(this.options.allowedHosts) && this.options.allowedHosts.includes("all"))
+ ) {

What do you think?

all and other hosts are mutually exclusive, I don't think there would be a use case for specifying other hosts with all 🤔 Maybe this would be the case for auto when we need to allow localhost along with other hosts

I think it was mistake adding auto (because we already allow to handle from localhost/ip/etc), we should revisit this in the next major release, I will finish PR

if (typeof options.bonjour === "undefined") {
options.bonjour = false;
} else if (typeof options.bonjour === "boolean") {
