From RFC 7622:
> Implementation Note: Reuse of the IP-literal rule from [RFC6874]
> implies that IPv6 addresses are enclosed within square brackets (i.e.,
> beginning with '[' and ending with ']'), , which was not the case with
> the definition of the XMPP address format in [RFC3920] but which was
> changed in [RFC6122].]]> Kim Alvefur <zash@zash.se> Sat, 14 Mar 2026 01:16:14 +0100 util.jid: Validate domainparts using IDNA or as IP literals (fixes #1903) http://hg.omfa.de/prosody-hg/log/863dd118f8e8/util/jid.lua
RFC 7622 defines the domainpart as:

> domainpart = IP-literal / IPv4address / ifqdn

Nameprep allows a number of characters that are not legal in DNS
names, such as U+20 " ", colon, slash, brackets, parenthesis.
Notably an IPv6 literal domainpart has the form "[db8::abc:123]", but
the brackets are not valid in IDNA, hence the separate checks for this.

From XEP-0106 §2. Requirements:
> in certain circumstances, the escaping character itself ("\") might
> also be escaped

Later in §4.2 Address Transformation Algorithm it is stated that the
backslash would only be escaped if it forms an escape sequence. Thus
'\foo' is unaltered but '\20' must be escaped into '\5c20'.
