Some of the domains registered included LilbetDiana.com and LiliDiana.com, The Telegraph reported.
The Duke and the Duchess chose their second child’s name as a tribute to Harry’s grandmother, the Queen, whose family nickname was Lilibet.
The baby’s middle name, Diana, was a tribute to her late grandmother, The Princess of Wales.
Royal expert Ingrid Seward claimed the Queen would not break away from royal tradition of neutrality to “reveal her feelings” about Harry and Meghan’s choice.
She told Express.co.uk: “I think the Queen will remain impassive about both the behaviour of the Sussexes and the naming of their baby girl Lilibet.
“Whatever she may think privately she will not reveal her feelings.
“It is personal and I feel certain she will keep it that way whatever they do.”
The Sussexes refuter earlier reports that they had not asked Her Majesty’s permission to use the name.
A spokesperson for the pair confirmed that during a conversation with the Monarch, the Duke “shared their hope of naming their daughter Lilibet in her honour”.
They added: “Had she not been supportive, they would not have used the name.”
The couple’s Archewell Foundation website released a statement announcing the birth of Lilibet Diana and confirming that both Meghan and the baby were in good health
The statement read: “It is with great joy that Prince Harry and Meghan, The Duke and Duchess of Sussex, welcome their daughter, Lilibet ‘Lili’ Diana Mountbatten-Windsor, to the world.
“Lili was born on Friday, June 4 at 11:40 am in the trusted care of the doctors and staff at Santa Barbara Cottage Hospital in Santa Barbara, CA. She weighed 7 lbs 11 oz.
“Both mother and child are healthy and well, and settling in at home.”
The statement also explained the inspiration for both of the newborn’s names.
