World's Longest Single Word Domain Names

I guess this is the longest single word domain name.

http://www.llanfairpwllgwyngyllgogerychwyrndrobwyllllantysiliogogogoch.com

This is Welsh and it means "St Mary's church in the hollow of the white hazel near a rapid whirlpool and the Church of St Tysilio of the red cave"

Cool but the longest domain name is:

www.tax.taxadvice.taxation.irs.tax-services.taxrepresentation.taxpayhelp.internalrevenueservice.audit.taxes.com

I guess

Although it's not a single word, it's from a company.
the first things were subdomains.

Anyway, this one is supposed to be the longest for .com (63 letter limit)

www.thelongestdomainnameintheworldandthensomeandthensomemoreandmore.com

There is also an longest email address, I have one, I registered one for myself long time ago, url for this email is:

www.abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijk.com
It's entire alfabet actually... funny, and then you can open yourself there an email like:
