They use good old decimal values. IPv6 will use something like <a href="http://2001:0db8:85a3:0000:0000:8a2e:0370:7334/" title="http://2001:0db8:85a3:0000:0000:8a2e:0370:7334/" rel="nofollow external">2001:0db8:85a3:0000:0000:8a2e:0370:7334</a>. There are valid ways to short some of them. One group of consecutive zeroes within an address may be replaced by a double colon. For example, <a href="http://fe80:0:0:0:202:b3ff:fe1e:8329/" title="http://fe80:0:0:0:202:b3ff:fe1e:8329/" rel="nofollow external">fe80:0:0:0:202:b3ff:fe1e:8329</a> becomes <a href="http://fe80::202:b3ff:fe1e:8329/" title="http://fe80::202:b3ff:fe1e:8329/" rel="nofollow external">fe80::202:b3ff:fe1e:8329</a>
