How do I edit the hosts file on my iPhone?

[8_hours_ago]

I use AdBlock https://www.adblockios.com on iOS which runs a local DNS server that can blackhole domains. It doesn't work well on very large host files so I gave up trying to import https://github.com/StevenBlack/hosts, but it does work well for smaller lists.

Probably not the answer you are looking for but:

(1) Install "1Blocker X" -- not free but it's cheap. (2) It has a huge number of rules and protects your Safari pretty damn good. (3) You can disable the existing rules if you so choose. (4) You can add new ones based on URL regexes or CSS rules.

I am still using it actively both on my iPhone and iPad, one of the best investment in apps I ever did.

Jailbreak it, install openssh, ssh in and edit /etc/hosts. There's also packages in Cydia that add adblock lists to your hosts for you.

You fire up vi and load /etc/hosts /s
