Toot

Written by ShadSterling on 2024-10-05 at 16:56

Just learned that there's a place named Llanfair­pwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch, which has a website at https://www.llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.co.uk/

Which makes me wonder, is there a limit on the length of a DNS name? Are there DNS implementations that will malfunction on a name that long?

@ShadSterling

Apparently the whole thing can be no more than 253 characters total including dots but there can be no more than 63 characters between dots. This one barely makes it at 59 characters.

@AdrianRiskin nice! If you follow the link it has another link for “upper” (“uchaf”) llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, which is exactly 63 characters: https://llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochuchaf.com

They call it the longest valid domain name, I didn’t realize it was also the longest allowed
